A/n: Okay so I know that I've done proposal imagines before but I really like doing them. Also, I know that it's not August sixteenth, but let's pretend that it is, okay? Anyways, I hope that you guys enjoy this imagine. Okay, without further ado, let's begin!

I've been dating the singer and songwriter Shawn Mendes for three and a half years. I know that he's the one that I want to spend the rest of my life with and he's told me that he wants to spend the rest of his life with me too. He told me back in the beginning of the year that by the end of the year we would be engaged. It's now August, and I just really at least want to be engaged to him so I can marry him.

I waited backstage with Shawn. He has a concert in Boston tonight, and we live in the Boston area now. I had just been in one of his q and a sessions where, after him and I gave each other a quick kiss, someone yelled for him to marry me already. He said that he would definitely wife me up someday, sooner rather than later, but I couldn't help but wonder when that would be. Shawn was rubbing my back when there was a knock at the door.

"Come in!" He said, and his parents, Karen and Manny, and his sister, Aaliyah, followed by my parents and my brother, walked in.

"Hi!" I said. I hadn't seen any of them in a while since I had been on tour with Shawn this summer. I hugged my family as Shawn hugged his family, and then I hugged his family as he hugged mine.

"How are you guys?" Shawn asked them as we all sat down.

"We're good. How are you guys?" Karen asked. I smiled at Shawn, who was already smiling at me.

"We're good. Are you having fun on tour with me babe?" Shawn asked and I nodded.

"Yeah." I said. I wondered if he remembered that we had met four years ago today - if he did remember, he had yet to say anything. Shawn kissed my cheek and I smiled. Soon, it was time for Shawn to go on stage. I gave him a quick kiss and then stood on the side of the stage with my family and his. Towards the end of the concert, the music stopped and Shawn began to speak.

"So, four years ago today, I woke up after playing here the night before and went to a local Dunkin Donuts. I had never been to Dunkin Donuts before, so I was going to ask the girl at the front of the line what I should get. The girl got her drink, turned around and when I saw her, I fell head over heels for her. I remember thinking right away that she's the one for me. She came up to me, and asked for a picture and I said yes. I asked her what her name is and she said 'Y/n Y/l/n.'" Shawn said and he had to pause for a moment to let the crowd cheer. "I asked her what to get, and after I ordered the drink, I walked back over to where she was and asked her out on a date. She said yes, thank God, and then we sat down and talked for two hours. Since it's the anniversary of the day that we met, I would love to bring her on stage. Y/n will you come on stage please?" Shawn asked. I looked at Andrew Gertler, Shawn's manager.

"He wants me up there?" I asked. Andrew nodded.

"Yup." Andrew said with a smile. Shawn was now walking towards me and held his hand out for me to take. I took his hand, and as our skin touched, I felt electricity spark through me, yet I felt safe and warm at the same time as he led me onto the stage where someone had put a chair.

"What are you doing?" I asked. He just kissed my cheek and smiled at me. He pointed at the chair.

"Take a seat honey." He said.

"Okay." I said. He then went over to the microphone again.

"Y/n and I really love this song, so I wanted to play it for her. It's called Love Someone by Lukas Graham." Shawn said and I smiled as he began to play it. Once he was done playing it, I stood up to give him a hug. He handed his guitar to Zubin, and I saw Zubin give him something, which he put in his pocket. Shawn then grabbed the microphone, walked back over to me and kissed my forehead.

"That was beautiful." I said. He took one of my hands in his and smiled at me. He put the microphone up to his mouth so everyone could hear him.

"Y/n, my darling girl, I love you. I love you more than words will ever be able to describe. You make me happier than I've ever been in my whole life and I'm the luckiest man alive because of you. I love every single thing about you. You have the kindest heart and the sweetest soul. You're my best friend, my soulmate, my rock, my everything, and I don't know what I would do without you. You know me better than anyone else, and you know everything about me, even my deepest secrets, things that I've never told anyone. So, with all of that said, Y/n Y/m/n Y/l/n," Shawn said before pulling out a ring and getting down on one knee. I clapped my hand to my mouth as I began to cry.

"Oh my God." I said. The crowd was going nuts so Shawn had to put his finger to his mouth to get them to quiet down.

"Will you marry me?" He asked with a smile that gave me butterflies. I nodded and took my hands away from my mouth.

"Yes! Yes a million times yes!" I said. Shawn's smile widened and he slipped the beautiful ring onto my finger. He stood up and held my face as he kissed me. I felt butterflies erupt and fly around in my tummy, I felt sparks shoot through my body like fireworks, and I felt my heart race as if I had just run a marathon. We pulled away and smiled at each other. Shawn then put one of his arms around me as he put the microphone up to his mouth so he could speak.

"We're getting married!" He said and the fans cheered. He then turned to me and hugged me.

"Oh my gosh this is amazing." I said. He kissed the side of my head and then pulled away from the hug a little but kept an arm around me as he spoke into the microphone again.

"So I'm not exactly sure of where everyone is, but Susie is here, Grace is here." Shawn said as he began listing loved ones that he had invited to the show.

"Oh my gosh." I said when he was done. He smiled at me.

"I have one more song that I want you on the stage for, but I don't want to sing this one, I want to dance with you to it." Shawn said. Marry You by Bruno Mars started to play and I smiled as he put the microphone back on the stand and came over to me.

"Shawn, we're both terrible dancers." I said with a laugh as he took my hands and we started dancing.

"Then we'll both be terrible dancers together." He said and I smiled. He pulled me close to him as he wrapped his arms around my shoulders and I wrapped my arms around his waist as we kind of just jumped around and laughed at how goofy we most likely looked. He then moved his hands so he could pick me up. I wrapped my legs around his waist and his hands went underneath my bum and he danced around as he held me. I laughed and so did Shawn. The song came to an end and he put me down.

"I love you." I said. He hugged me tight.

"I love you too darling." Shawn said. I then backed away from the hug a little.

"Can I ask you a question?" I asked. I felt nervous. He could sense this so he rubbed my sides.

"Yeah of course." He said.

"Would it be okay if I took your last name when we get married?" I asked. His eyes widened.

"You, you want to take my last name?" He asked. I nodded.

"Yes, but only if that's okay with you." I said. He smiled and nodded as he pulled me in for a hug.

"Yes of course you can take my last name! Oh my gosh of course." He said. I gave him a kiss. He then held my hand as he walked over to the microphone, still smiling. "Guys, she's going to take my last name when we get married!" Shawn said and the crowd cheered. I hugged him.

"I love you." I said.

"I love you too." He said. He then walked me to the side of the stage and mine and his families hugged me as he went back over to the microphone.

"Congratulations!" Everyone said and I thanked them.

"God I love that girl." Shawn said and I laughed. After the concert, Shawn came over to me and hugged me.

"I love you. Oh my gosh Shawn we're engaged!" I said as we hugged. He kissed the side of my head.

"I love you too and yes we are!" Shawn said. He hugged his family and mine and then we all went back to mine and Shawn's house. We stayed up until two in the morning, when Karen, Manny, and Aaliyah went to their guest bedrooms, my family went home, and Shawn and I went upstairs to our bedroom.

"It all makes sense now." I said as we got into bed but sat up and leaned against our headboard.

"What does babe?" Shawn asked as he pulled me close to him.

"The fact that you wanted to have me take my promise ring off so you could get it cleaned and why both of our families showed up." I said. Shawn smiled at me and kissed my cheek.

"I'm so happy honey." Shawn said. I smiled at him.

"Me too. Want to go to sleep now?" I said and asked.

"Yeah. Come here darling." Shawn said. I turned off the light that was next to my side of the bed, and laid down and cuddled up to Shawn. He laid on his back as I rested my head on his chest and he wrapped his arms around me.

"Good night future hubby. I love you." I said. He kissed the top of my head.

"Good night future wifey. I love you too." He said, and with that, we fell asleep as an engaged couple. I love Shawn so much, and I'm so happy to be engaged to him.
