Dedicated to my best friend, BellaSmith03. I hope you enjoy this, cause I worked really hard on it, just for you...❤

Finally, the day you had been waiting for since you were a little girl was here. It was the day of your senior prom. So far, the day had gone quite well. You went to the hair salon and the stylists had done an amazing job. They perfectly pulled off the look you were going for - a sleek, straight style with your short, bobbed hair that had a few blue streaks in it.

Once home from your hair appointment, you got right to work on your makeup. You settled on bright turquoise eyeshadow with silver liner and a pale pink lip color. Then you snapped a few selfies and slipped on your jaw-dropping prom dress - a shocking aquamarine number with a mermaid silhouette and a halter neck.

( This is what your dress looks like )

You glanced in the mirror and were very satisfied with your appearance. "Just wait till San sees me later," you thought, smirking to yourself. Speaking of your prom date, where was he? It was almost time to leave for pictures at the park. "Oh well," you sighed, "he'll get here soon." While waiting for San, you decided to keep yourself occupied by thinking back to how he had asked you to prom.

( Flashback )

You and San's love story went back really far - to the time when you were babies. Your parents were friends, so they frequently had you two play with each other. By the time you entered preschool, San and you were inseparable. The two of you practically grew up joined at the hip, always in the same classes, having sleepovers often, and you even took dance lessons together. Then middle school happened.

Both of you developed feelings for each other, but being new to love as you were, the two of you ended up waiting till freshman year to confess. You and San then became the power couple of your high school, being homecoming queen and king, having heated makeout sessions against your lockers, and, in general, always being all over each other. Of course, San, being the dramatic guy that he is, pulled off a promposal you would never forget.

You had just stepped out of physics class when you were practically ambushed by Wooyoung and Mingi.

"Y/N, come with us," they said, basically dragging you through the halls with them. Unfortunately, you had no choice but to be dragged along with them. But when you saw who they were taking you to, you instantly became excited.

It was San, standing out on the football field with a bouquet of red roses in his hand. He was surrounded by his five other friends, who were holding a giant sign that said,"Y/N, will you go to prom with San?"
You ran over quickly and practically tackled San with a huge hug.

"So, I take this response to be a yes?" San joked, wrapping his arms tightly around your waist and kissing you gently on the forehead.

"Of course it is!" you exclaimed. "San, thank you so much! This is so sweet."

"Aw, thanks," San said, blushing. "Anything for you, Y/N."

Suddenly, you were snapped out of your reminiscing by the sound of a doorbell. You jumped and internally screamed,"Aah, he's finally here!" You hurried downstairs and opened the front door to see San, breathtaking as usual, standing there. He truly was quite a sight to behold.

San was wearing a bright white, almost blinding suit that made him practically look like an angel ( not that he wasn't ). Your boyfriend, being the over-the-top guy that he was, had lots of flashy silver bling on his suit that almost turned him into a disco ball. San's beautiful, blonde hair flowed over his forehead effortlessly, while his soft, tender lips were formed into an adorable grin. His dimpled cheeks flushed when he looked at you with his gorgeous, twinkling eyes. You were sure you had never seen a more beautiful human being in your life.

( This is what San looks like )

Finally, San broke the silence and said,"Wow, Y/N, you look so amazing! Not that you don't always look great, of course," he added.

"Aw, thank you!" you replied, blushing. "You don't look too bad yourself." The two of you would have just stood there gazing at each other, but then you said,"San, we have to get to the park for pictures soon!"

"Oh right! How could I forget? Let's go, Y/N," he replied, grabbing your hand and running down the sidewalk to get to the community park.

( A few hours later [ after pictures and dinner ] )

"Y/N, there you are!" your best friend Alia exclaimed, running to give you a hug.

"Hello to you, too," you replied, returning the embrace.

"You look so pretty!" Alia said. "Now hurry up and get on the party bus so we can get to the dance." She practically pushed you and San onto the bus.

Now, you and your boyfriend were finally on your way to the last high school dance the two of you would ever share. But not wanting to let reality sink in, you made your way over to your other best friend, Sarah, who was holding hands with her boyfriend, Seonghwa. "Hi, Sarah," you said.

"Y/N, you're here!" Sarah squealed, tackling you with a giant hug. "I love your dress so much, that color is perfect for you."

"Thanks," you replied. "I like yours, too."

"Well, I'll let you two catch up," San said, going over to talk with Seonghwa and Alia's boyfriend, Wooyoung.

Sarah motioned Alia over to join the two of you. Then you and your two friends spent the rest of the ride giggling, chatting, and gossiping about anything and everything, the topics of conversation ranging from your dresses to your boyfriends. But soon the ride ended, and you were finally at prom. You grabbed San's hand and ran inside the hotel with him, making your way to the ballroom and going inside to see it lavishly decorated. This year's theme was galaxy, and the decorations were truly out of this world.

Large, twinkling stars in magnificent hues of blue and purple hung from the ceiling, giving off the appearance of falling stars. The room was dimmed, so it was like walking into an illuminated black hole. There was a flashing disco ball over top of the dance floor that changed color every few seconds. Lining the walls of the ballroom were bunches of star-shaped, shiny balloons. And projectors caused different images to appear on the dance floor, walls, and ceiling, such as stars, moons, and planets. All in all, it was as if you and San had stepped into another galaxy - literally.

You and your boyfriend would have just stood there gaping at the out-of-this-world decorations, but your favorite song, Sunshine, started playing, so you took San's hand and pulled him onto the dance floor. Song after song played, and you began to get tired, so you left the crowd dance floor to take a short break and talk to your friends. "Hi, guys," you said, walking over to Sarah and Alia, who were currently giggling about something. "Oh, what's up, you two?"

"Ask her," Alia pointed to Sarah, still giggling.

"What happened?" you questioned.

"Oh, nothing," Sarah said, blushing furiously.

"Tell me," you persisted.

"Oh my gosh, Y/N! It was the most romantic thing ever! So, when Spring Day was playing a few minutes ago, Seonghwa told me that he loved me! And then he kissed me for the first time," Sarah sighed while she retold the story.

"Aw, that's adorable!" you exclaimed, giving her a hug. "I'm so happy for you."

"So, Alia," Sarah said,"has Wooyoung done anything cute yet?"

"No, not yet," Alia sighed.

"Oh, I bet he will soon," you assured your friend. "Speaking of Wooyoung, where is he, anyway?"

"Oh, he's probably off having a dance battle with Seonghwa to see who can be the sexiest," Alia said, laughing.

"As usual," Sarah added.

The three of you had a good laugh, but then you noticed that San was nowhere to be seen. "I wonder where he is - " but you were cut off by the sound of his voice echoing across the room.

"Hello everyone, can I have your attention, please?" The room instantly got quiet, so San continued. "So, my two friends and I," San motioned to Wooyoung and Seonghwa who were standing beside him, "have a very special surprise for three very special girls. Could Sarah, Alia, and Y/N come up here, please?"

Your two best friends looked at each other, squealed, and ran up to the DJ booth while you followed them as if in a daze. "What was San planning?" you thought to yourself.

Once you reached the booth, San said,"Ok, so my friends and I have a song that we wrote for the three of you, so without any further ado, let's get started."

Slow, entrancing music began to play, and the three boys started singing in their beautiful voices. Seonghwa's voice was husky, but light, and slightly deeper than the other two's. Wooyoung's was high and clear, but very powerful. And San's was truly indescribable. It was slightly high, and it was light and airy. But his voice also had a strong, stable quality to it. You were so mesmerized, the song seemed to last for only a few seconds. But you were pulled out of your trance by the sound of your boyfriend's voice.

"So, that song was called Star 1117. The reason for that seemingly odd title is because on that date, almost seventeen years ago, I met my amazing, beautiful girlfriend, Y/N. We grew up together, and around middle school, we both developed feelings for each other. So, at the beginning of freshman year, I asked her to be my girlfriend, and the rest is history."

At this point, you felt like you were dreaming, but San continued on. "And, of course, we can't forget Sarah and Alia. Both Seonghwa and Wooyoung have something to say to them, also." San passed the microphone to his two best friends, who each gave a little speech, too. But you barely heard a word. You were in complete shock because you couldn't believe that this was actually happening to you.

After Seonghwa and Wooyoung were done talking, San continued once more. "And so, on this very special, memorable night, I have an important question for my lovely girlfriend. Y/N, will you come over here, please?"

Your best friends practically had yo shove you over to San. When you did finally get to your boyfriend, he pulled something out of his pocket and knelt down, almost giving you a heart attack.

"A-are you pr-proposing?" you managed to squeak out while stuttering.

San shook his head and said,"No, I'm not proposing - at least not yet, anyway. I think we're a little too young for that, don't you?" He raised an eyebrow, causing you to giggle and blush.

"But I am telling you that I love you and I always will. Y/N, I don't know what will happen in the future, but I do know one thing for sure. I want to be with you, no matter what. I promise," San added, opening the little box in his hand. Inside was a magnificent, sparkling silver ring, which he pulled out and slipped on your finger.

"This is a promise ring. In the act of giving it to you, it means that I promise myself to you, no matter what. So, Y/N, what do you say? Will you forever be my star?" San asked, referring to the song he had sung earlier.

As you hugged him tightly, you said,"Yes, of course I will be, San! I love you, too," barely managing to hold back your joyful tears. The two of you broke apart, and San kissed you on the cheek. The crowd gathered around you burst into applause, and your best friends ran over to congratulate you.

Grabbing your hand, San pulled you to the middle of the dance floor and put his arms around your waist, signaling other couples to do the same. Getting the message, the DJ started playing a slow ballad called Promise, which was one of your favorites. You wrapped your arms around San's neck loosely and leaned into him, causing your boyfriend to pull you even closer to him. Then the two of you started dancing.

San sang softly in your ear, "No one take you down, you and I promise, no one take you down, don't worry, I'll be there, shining as bright as a star..." At these touching words, which were your favorite lyrics of the song, you briefly pulled away, but leaned back in and kissed him like you never had before. It was as if millions of fireworks exploded when your lips connected. You had never been one who was good at expressing your feelings, so you hoped this kiss would make up for your lack of words after San's beautiful speech earlier.

The kiss certainly seemed to work, as San brought you closer to him, tightened his hands around your waist, and intensified the movement of his lips against yours. The two of you continued to kiss slowly, yet passionately, until the song ended and a new, much faster one played. You took that as your cue to exit the dance floor with San so you could go talk for a little while.

As you went to go sit down, you saw Wooyoung and Seonghwa having yet another dance battle while Sarah and Alia cheered them on. After talking with San for a bit, you dragged him back to the dance floor and the two of you joined the others to truly dance the night away. However, the night soon came to an end, and your senior prom was over. All six of you got back on the party bus, exhausted, but still quite full of energy.

"Well, I don't know about you guys, but I think that was the best prom ever," Wooyoung piped up. Everyone agreed enthusiastically, and Wooyoung continued. "But that was because I got to spend it with the best person ever," he said, looking at Alia with a smirk.

"Oh, stop it, you big flirt!" Alia exclaimed, playfully punching her boyfriend on the arm.

"But you love this big flirt, don't you?" he shot back. Alia rolled her eyes, but reluctantly nodded, and then giggled when Wooyoung leaned in to kiss her on the cheek. Apparently, that wasn't enough for Wooyoung, because next, he pulled his girlfriend onto his lap and started making out with her intensely.

"Yuck, get a room, you two!" you and San burst out at the same time, throwing the couple looks of mock disgust.

Wooyoung surfaced briefly only to shoot back,"No, the only ones who need a room are Sarah and Seonghwa," before going back to kissing Alia.

You looked over to see Sarah straddling Seonghwa, and the two were engaged in an even more intense make out session than Wooyoung and Alia, if that was possible. Apparently Seonghwa, as usual, wanted to make everything a competition with Wooyoung, although this was honestly ridiculous. "Ugh, will you guys stop already!" you burst out. "My eyes can't handle this."

"Yeah, neither can mine," added San.

You guessed that your friends got the message, because they promptly stopped, looking quite embarrassed. Then Wooyoung piped up,"Well, Y/N, I think that you and San are the ones who need to get a room." You blushed and San pulled you closer to him, smiling with his dimples in full glory. "Yeah, it's not like I didn't see you two getting nice and cozy on the dance floor earlier," Wooyoung continued, smirking.

San rolled his eyes and said,"Ok, I think it's time for a subject change." Everyone agreed, so you and your friends rehashed everything that had happened that night - who danced with who, your favorite songs and funny moments, and everyone's looks. But then the bus reached the neighborhood where all of you lived, which meant that the night was finally, but unfortunately, over.

The six of you got off the party bus and walked toward your houses, laughing and talking the whole way. You got to Sarah's house first, so you and Alia hugged her and Seonghwa kissed her goodnight. Then you and the others walked to Seonghwa, then Alia's, and finally Wooyoung's house, telling them all goodbye. Now it was just you and San.

He walked you up to your front door, holding your hand the whole time. "Goodnight, Y/N," San whispered in your ear, kissing you tenderly on the cheek. "I had an amazing time tonight."

"I did, too," you replied, leaning in and hugging him tightly. "I wish it wasn't over."

"Me too," said San, pulling away from the embrace. "But, it really isn't over until I kiss you, you know."

You giggled, and San took that as a cue. He kissed you as if he never wanted to leave you, and it was the last kiss you would ever have together. As the two of you kissed, you realized how lucky you were to have San in your life. You hoped that the two of you would always be together, no matter what.

Unfortunately, the kiss couldn't last forever, so you and San broke apart. But he gave you another hug, saying,"I love you," as he did so.

"I love you, too, San," you replied. San let go of you reluctantly, pecked you on the cheek, and walked off, waving over his shoulder. You waved back and went inside, feeling the happiest you had ever felt in your life. Who cared about the cliche, this was truly the best night of your life and was one that you would remember forever.
