A/n: Not going to lie, there's a person that I have in mind whenever I mention Johnny, and I so want to use his picture in here but I won't because he doesn't know that I write these, so I'll just use a picture of Shawn sitting on his jeep instead. It'll make sense in the story, I promise. Also, let's pretend that it's April of 2021, shall we? Anyways, explicit language in this one. Please enjoy this imagine. Okay, without further ado, let's begin!

"Keep coming, keep coming, keep coming, okay STOP!" Johnny, my neighbor yelled. I couldn't believe that he was letting my boyfriend, Shawn Mendes, do this. But Johnny had wanted to throw me a birthday party for my twenty second birthday, so I guess the way that we would blare our music would be up to Johnny. That's how Shawn and Johnny came to the agreement that Shawn would drive his jeep into Johnny's backyard.

"Okay, now blare some music babe!" I yelled as I videotaped this. I couldn't believe that Shawn's jeep was in Johnny's backyard. Would Anne, Johnny's mother, be happy about this? Most likely not, but Johnny said that it was okay. Shawn started to blare Sorry Not Sorry by Demi Lovato and Johnny, our neighbor Liz, and I all cheered. Shawn stepped out of his jeep and smiled at me as Johnny handed him a beer. He came over to me and I stopped recording.

"Hey birthday girl. How are you doing?" He asked as he wrapped an arm around my shoulders. Johnny handed me a Coors Light.

"I'm doing good. What about you?" I asked. Shawn kissed my cheek.

"I'm good." He said.

"Guys, I want all of you to get as shit faced as possible. You guys can sleep over tonight and Shawn's jeep can stay back here. Just please, get drunk." Johnny said. I laughed and then laughed even harder when I looked over and saw Shawn chugging his beer.

"This is going to be great." Shawn said and I laughed and nodded.

"I hope my mom doesn't come over and yell at us." I said as I looked at my house which was right next to Johnny's.

"She knows that we're having the party, it's fine babe." Shawn said. I nodded and turned to him.

"Thank you for coming to town to celebrate my birthday." I said. Shawn smiled at me.

"Anything for you my love." He said. He then put his lips on mine. I felt my heart race as if I had just run a marathon, I felt sparks shoot through my like fireworks, and I felt butterflies erupt and fly around in my tummy.

"Alright, let the girl breathe Shawn." Johnny said. Shawn and I pulled away and blushed.

"Guys, let's have a bonfire!" Liz said. We all smiled and nodded. I sat on Shawn's lap as Johnny got the fire started. Johnny then held up his beer as a toast.

"Cheers to this girl that I've know since she was in the womb for turning twenty two. Happy birthday Y/n!" Johnny said. I laughed and smiled. Everyone else cheered.

"Happy birthday!" Shawn and Liz said.

"Happy birthday!" Tommy, Liz's husband yelled. I looked at him.

"Thanks Tommy!" I said. Shawn kissed my shoulder. My birthday had actually been a few days before this, but we all had to coordinate our schedules and we wanted to have this party on a weekend. I turned in Shawn's lap. He had finished the first beer and was on the second one. I kissed his cheek and he smiled at me.

"Hey there my love." He said.

"Hi there honey." I said. As the night went on, all of us, except for Liz and Tommy, downed our beers and shots of fireball and shots of vodka. Shawn and Johnny were the most drunk and I was a bit tipsy.

"YOU ARE THE ONLY EXCEPTION!" Shawn yelled as he sang along to the song by Paramore. I got out my phone and took a picture of Shawn and Johnny singing to each other while drunk. I would have to post that when I wasn't this tipsy.

"Y/n! Come here!" Johnny yelled. I did as told.

"What's up?" I asked. Johnny took my phone.

"Liz, can you take a picture of us please? Shawn and I are going to make a Y/n sandwich." Johnny said. Oh God. I knew what that meant.

"Sure." Liz said as she took my phone. I stood in between Johnny and Shawn and then they pressed themselves against me so they were squishing me as they laughed.

"Can't breathe." I said. That's when they finally stopped squishing me. I stuck my tongue out at Shawn and he laughed.

"I got the picture!" Liz said. I smiled and looked at it. Even though they were squishing me, I loved the photo. All of our smiles were huge and you could see that Shawn and Johnny were holding their beers.

"Do you guys mind if I post this?" I asked.

"No that's fine honey." Shawn said.

"Yeah that's fine." Johnny said. I smiled and posted it to Instagram.

"Shawny and Johnny made a Y/n sandwich!" I captioned it.

"Let's take a group photo!" Johnny said. Shawn took my phone and I leaned on him and smiled at my phone. Liz stood next to me with Tommy behind her, and Johnny on the other side of Liz. Kristen, Johnny's fiancé who had just joined us, stood in front of Johnny. We all agreed that I would post it on Instagram since it was on my phone.

"Some of my favorite people and I!!!" I captioned it.

"I love it." Shawn said. Suddenly, Perfect by Ed Sheeran started playing. I set my beer down and so did Shawn as we began to dance. I smiled at him.

"Are you having fun my love?" I asked. Shawn smiled.

"With you? Always." He said. I smiled and kissed him again. I then realized something. Kristen and Johnny were engaged, Liz and Tommy were married, and I had a promise ring from Shawn. I kissed Shawn quickly.

"Want to walk around the backyard a bit?" I asked. Shawn nodded.

"Yeah. Everything okay?" He asked. I interlaced my fingers with his. As soon as our skin touched, I felt electrified, yet I felt safe and warm at the same time. Shawn and I haven't even been dating for a year and a half, but I know that I want to marry him. I've known that for a long time.

"When do you think we'll get engaged?" I asked. Maybe the alcohol was hitting me a little more than I had realized. Shawn stopped walking and so did I. We looked at each other.

"I thought that we agreed that we wanted to be together for about two years before we got engaged." He said. I nodded and wrapped my arms around his shoulder.

"Yeah. I just... you're the one Shawn. I love you and I want to spend the rest of my life with you eventually." I said. Shawn rested his forehead against mine and rubbed my back.

"I love you too, and don't worry baby girl. We'll spend the rest of our lives together, I promise." He said.

"Shawn, what if we end up like those other famous couples and split up?" I asked. He held me closer to him.

"That won't happen baby girl. We're never going to split up, okay? I promise you, right here, right now, while I'm kind of drunk, that we'll never split up." He said. I nodded.

"Okay." I said. We then went back to everyone.

"Everything okay?" Liz asked. Shawn and I nodded. Soon, I had drank five more beers - causing Johnny to cut off my beer intake. I was drunk from the five beers and I don't even know how many shots of both fireball cinnamon whiskey or vodka. I looked at Shawn and smiled.

"I'm so fucking in love with you." I said. Shawn smiled at me, his arm wrapped around my waist.

"Well I'm so fucking in love with you too." He said. Tears formed in my eyes and spilled out onto my cheeks.

"No, like I really love you. I love you so much Shawn, oh my gosh." I said as I cried. Wow, I was drunk. Shawn pulled me in for a hug.

"It's okay babe, you don't need to cry about that. Why are you crying about how much you love me?" He asked. I looked at him as I cried. Everybody was watching but I was too drunk to care.

"I just, I don't know. I love you. I love you. Oh my gosh you're my best friend, I love you so much Shawn. You're my everything. And like, I can't wait for our honeymoon when you take my virginity -" I started.

"Okay! So yeah, I love you too." Shawn said as everyone laughed.

"But wait, Shawn, like, we're soulmates, right? And we're going to spend the rest of our lives together?" I asked. Shawn nodded.

"Yup. We're going to grow old together." He said.

"See? Someday you're going to get me pregnant, and I'll have your babies. I just love you so much Shawn, oh my gosh. I mean seriously, how could you not love this face?" I asked as I held his face in my hands.

"You're silly when you're drunk." He said.

"I love you." I said. Shawn gave me a kiss.

"I love you too babe." Shawn said.

"Yay!" I said and everyone chuckled. We partied for a good portion of the night. The next morning I woke up on Johnny's couch with Shawn laying beside me. My head was pounding and I ran to the bathroom to puke. When I stepped out of the bathroom, Johnny was in the kitchen. He held something in his hands.

"Need some aleeve?" He asked.

"Shhh, stop yelling." I said. He chuckled.

"I'm not yelling, you're just hungover. Here, this will make you feel better." Johnny said as he handed me the pills. I got some water and took the pills.

"Thanks. Not just for the pills, but also for the party." I said.

"No problem." He said. Once the meds had kicked in, I check my phone. Shawn had posted a picture of him holding me close to him as I cried.

"Here's a picture of me comforting my very drunk girlfriend as she cried about how much she loves me." Shawn captioned it. I laughed quietly, not wanting to wake Shawn up. I looked at some pictures that Kristen had sent me. In one of them, I was holding Shawn's face as I kissed him. In another one, I was kissing Johnny's cheek as he laughed. In the last one, it was me looking very excited to see Dave, Johnny's dad, as I smiled really wide and hugged him. I posted the pictures to Instagram.

"I'll be honest guys, I was so drunk that I don't even remember these moments. When did Dave come out? Anyways, I didn't realize that I get this touchy feely when I'm drunk. Oh well. Last night was HILARIOUS and so much fun! Thank you Johnny for the party!" I wrote.

"Good morning baby." Shawn said. I smiled at him.

"Good morning my love. How are you feeling?" I asked.

"Like my head is pounding." He said.

"Johnny has some meds that you can take." I said. Shawn nodded, gave me a kiss and then went and got some meds. He came back and smiled at me. We cuddled for a little bit.

"Hey babe, can you take a picture of me sitting on top of my jeep please?" Shawn asked. I nodded.

"Of course honey." I said with a smile. We went outside and Shawn sat on top of his jeep, smiled at the camera, and I took the picture. He got off his jeep and looked at the photo.

"Mind if I post your beautiful photo on Instagram?" He asked. I shook my head.

"No, that's fine." I said. Shawn kissed my cheek. He then posted the photo on Instagram and showed me the post.

"Sometimes Y/n's neighbor lets me park his jeep in his backyard so we can blare music and celebrate Y/n's birthday. Thanks Johnny! And to Y/n, my sweet girl, happy belated birthday. I know that we were both pretty drunk last night and I don't remember all of it, but I know that last night was wild and fun. I love you baby girl." He wrote. I smiled.

"You're so sweet and cute. In fact, you're the cutest person ever." I said. He chuckled.

"Nope, that's you darling. I know that I gave you your presents on your actual birthday, but I saw that you had your eye on something the other day, so I got it for you." He said as he opened up the door to his backseat.

"Shawn, you didn't have to do that." I said. He chuckled and then turned around, a little box in his hand.

"I know that I've given you a promise ring, and this isn't an engagement ring, but I saw you looking at it the other day so I thought that I would get it for you." He said. I took the little box from him and my eyes widened when I saw the opal cocktail ring. It was beautiful. I looked at Shawn.

"Shawn it's beautiful, but wasn't the price, like over a thousand dollars?" I asked. Shawn waved his hand like it was nothing.

"It's fine babe. You're worth every penny." He said. I hugged him.

"It's beautiful and I love it but I feel bad." I said. He rubbed my back.

"Why honey?" He asked. I pulled away from the hug and looked at him.

"You spent over a thousand dollars on me. I don't like it when you spend money on me." I said. Shawn rested his forehead against mine.

"It's okay baby. I love you, and I wanted to get this for you." He said.

"I love you too. Thank you for this, and well, for everything. Do you want to put the ring on me?" I asked. Shawn smiled and put it on me. I love Shawn so much and I'm so glad that we had a good time at the party.
