My fiancé is the singer and songwriter, Shawn Mendes, and today is the day that he is coming home from tour. In a couple of days, we're going to celebrate four years of being together. I sat on the couch, impatiently waiting for him. Soon, the door opened and Shawn walked in, with my brother close behind him. They were carrying his luggage in. Shawn smiled at me when he saw me and his smile alone gave me butterflies.

"Hey darling." Shawn said as he set his stuff down. I stood up and ran into his arms. He caught me and my legs went around his waist. He put his hands underneath my bum to hold me securely.

"You're home!" I said and Shawn nodded and kissed my cheek.

"I am. I have to help my future brother-in-law carry in my luggage." Shawn said as he set me down. I nodded.

"Okay. I'll be on the couch, or do you want help?" I asked.

"Go sit on the couch darling. I'll be right there." Shawn said and I did as told. I watched him and smiled. Soon, all of his luggage was inside and he thanked my brother before walking over to me. He sat down on the couch next to me.

"I've missed you so much baby." I said as I pulled him in for a hug. He hugged me back of course.

"I've missed you so much too." Shawn said. He then pulled away from the hug to plant kisses all over my face, causing me to laugh and squeal. He then kissed my lips. I felt sparks shoot through my body like fireworks, I felt my heart race as if I had just run a marathon, and I felt butterflies erupt and fly around in my tummy. Shawn and I pulled away and smiled at each other. I then remembered something.

"Oh! I have something for you!" I said.

"You didn't have to get me anything baby. You know that I don't like it when you spend money on me." Shawn said.

"I didn't have to pay for anything. Here you go." I said as I handed Shawn an envelope. He read what it said on the envelope.

"To: My future husband, from: your future wife." Shawn read. He smiled at me. "What is this?"

"Open it up and find out." I said with a smile. He opened it up and took out the letter.

"Is this a letter?" Shawn asked. I nodded.

"Yeah. Read it out loud baby." I said. He nodded, opened the folded papers, and began to read.

"To my amazing fiancé,

Shawn, it is currently two in the morning and I can't sleep. Why? Because I'm too excited. The love of my life, who I haven't seen in a while, is coming home tomorrow - well technically later today - and I absolutely can't wait to see you again. Because I can't sleep, I've decided to come into your office and write this letter to you, so I hope that you don't mind.

My love, you mean the world to me and I will never truly be able to express how I feel about you. You have been there for me through so many highs and so many lows and I can't thank you enough for that. You're the most amazing man that I've ever met, and I swear that you're magical or something. When we touch, I feel electricity spark through me, yet I feel safe and warm at the same time. When we kiss, my heart races, I get butterflies, and I feel sparks throughout my body.

You love to say to me that I'm the most beautiful girl in the world. Well, Mr. Shawn Mendes, did you know that you're the most handsome man in the world? You have the most beautiful pink, plump, lips, and whenever I wake up before you when we're together, I have to resist the urge to kiss you, and it's hard. I love the little scar on your cheek and the story behind it. It's so cute! You have such a boopable and cute nose, and I love to kiss it. I think that it's so cute that whenever I kiss your nose, you scrunch it up as you smile. And oh my gosh your smile. Oh Shawn, your smile could cure everything bad in the world, it can truly light up a room, and it never fails to give me butterflies, especially when I know that I've caused it.

My favorite thing about you physically would definitely, absolutely, one hundred percent, have to be your gorgeous eyes. Remember the first thing you said to me when we first met? You said 'I'm sorry, what? You have the most beautiful eyes I've ever seen.' and I must say, the same goes for how I feel about your eyes. Shawn, your eyes mesmerize me, they pull me in, and I never fail to get lost in them. Your eyes are like maze, but they're a maze that I don't want to find my way out of. I swear that it's like your eyes can tell me stories. They tell me how you're truly feeling.

My favorite thing about you that isn't physical, that isn't something that I can touch, is your soul. Oh my gosh Shawn, you have the sweetest soul that I've ever known. You have the kindest, and nicest, and sweetest, and most passionate soul ever. There's more to your soul, but that list is very long. Do you know what the definition of a soulmate is? A person ideally situated to another as a close friend or romantic partner - and yes I just looked that up. Shawn, you truly are my soulmate. I believe that in another life we were soulmates too, and maybe in our next lives we'll be soulmates again. I sure hope so, because my soul loves your soul. But as of right now, we're soulmates in this life, and I love that. Emily Bronte once wrote 'Whatever our souls are made of, his and mine are the same.' and that couldn't be more true about us.

Shawn, I love you so much that just a couple of months ago, I cried while watching a video of you - remember that? Remember how you ended the livestream when you saw that I was crying and then Facetimed me? Gosh I love you. I can't even put it into words, but I can try, so here goes.

Shawn Peter Raul Mendes, I have loved you from the moment that I laid eyes on you, maybe even longer actually, and I'll never stop loving you. I love you deeper than the deepest of oceans and higher than the highest of mountains. To say that I love you to Pluto and back is an understatement. Hell, to say that I love you to infinity and back is an understatement. I have fallen beyond in love with you in every way possible. I love you so much that my heart aches for you whenever we're apart, but then when we're reunited, my heart is happy. You make my heart smile.

You make me the happiest woman alive and I'm truly the luckiest girl in the world to be able to call you mine. When I'm with you, everything is better. I smile more, I laugh more - I squeal more when you unexpectedly pull me onto your lap or adorn my face with kisses. You shower me with nothing but love, affection, and gifts. The gifts, yes I do love them, but you know how I feel about you spending money on me. The affection that you shower me with, all of your hugs and cuddles and kisses - whether it's a kiss on the lips, on the cheek, on my forehead, anywhere - I love it and it just proves to me that you truly love me. Oh my gosh, the love that you shower me with is amazing. You constantly tell me that you love me and how much you love me. You always remind me that I should try to love myself, and I try to, just for you. I love how you always remind me that I'm your girl, and nobody else's. I love it when you refer to me as your girl, it makes me smile and blush, which you've probably noticed.

Shawn I love how you make me feel. When I was with my ex, he almost never called me pretty or beautiful or anything. In fact, as I've told you before, he told me to my face that I am NOT gorgeous. But you're constantly telling me how beautiful and stunning and gorgeous I am. Thank you for that. I love the fact that I could be wearing no makeup and either pajamas or sweats or whatever, and I think that I look like absolute garbage, but you smile at me and say 'Look at how beautiful you are.' or something similar to that, and I can tell that you mean it. I loved it when we were about to go to some awards show, and when you saw me in the dress - it was the one that was sparkly on top and then white at the bottom - you literally jumped into the air, clapped your hands together and yelled 'WOO! Damn am I lucky or what?' all while you smiled. You make me feel like I'm beautiful, and I know that you probably want to say 'That's because you are beautiful.' but you know how I feel about myself, so thank you for all of the millions of times that you've told me how beautiful or gorgeous or stunning I've looked. I love you for that.

Shawn, I can't thank you enough for everything. Thank you for being my best friend. Thank you for never failing to make me smile or laugh or both. Thank you for being my soulmate. Thank you for picking me, for choosing me. Thank you for reminding me that I am good enough for you when I don't feel like I am. Thank you for being my rock. Thank you for being my protector. Thank you for the endless amount of love that you give me. Thank you for all of the gifts. Thank you for all of the memories that we've made, and thank you for the ones that we haven't even made yet but I know we will. Thank you for being the love of my life. Thank you for asking me to be your wife, which I know will be the greatest honor. Thank you for being my everything, but most importantly, thank you for being you. I love you Shawn Mendes.

Love,

The future Y/n Mendes" Shawn read as happy tears ran down his face. He looked at me and smiled.

"Did you like it?" I asked. Shawn put the letter down and pulled me into his lap and of course, since I hadn't been expecting this, I squealed.

"Darling, that's the most beautiful thing that you've ever written. I love that so much, oh my gosh. That was amazing. Wait, did you, did you sign Mendes in cursive?" Shawn asked with his eyes wide all of the sudden. I smiled wide and nodded.

"Yup." I said.

"But you told me that the only thing that you knew how to write in cursive was Y/n Y/l/n." Shawn said. I nodded.

"Yes, that was true, but I've spent the last month learning and perfecting how to write Mendes in cursive since it's going to be my last name. I need to learn how to write it in cursive eventually." I said. More happy tears fell onto Shawn's cheeks and he hugged me.

"You're the most amazing woman ever, the most amazing person ever. Holy crap I love you. Thank you for that baby." Shawn said. I pulled away and smiled at him.

"I love you too honey and you're welcome. I didn't mean to make you cry!" I said. Shawn shook his head.

"They're happy tears, I promise." Shawn said. I leaned over and, just like he does to me sometimes, kissed his tears away.

"So you really liked it that much?" I asked. Shawn chuckled.

"My love, my darling, precious, love, I'm literally crying because that was so beautiful. Oh my gosh you never cease to amaze me." Shawn said. I smiled at him and kissed his lips. I then pulled away when I realized something.

"I just realized that there was something that I forgot to thank you for." I said. Shawn's tears had stopped by now.

"And what's that?" He asked.

"Thank you for the way that you look at me. Like right now, you have such a loving look on your face. Thank you for that." I said. Shawn smiled.

"Do you want to know why I look at you like that?" He asked. I smiled.

"Yeah, why?" I asked. He pulled me closer to him and brought his face so close to mine that I closed my eyes because I thought that he was about to kiss me.

"Because I love you more than anything and anyone in this world." He whispered. I could feel his breath on my lips and it sent shivers down my spine. I opened my eyes, smiled at him, closed my eyes again, and kissed him. He kissed back of course, and I felt the same feelings that I had before: the sparks, the butterflies, the heart racing, everything. Shawn and I kissed until we couldn't possibly kiss anymore, and when we pulled away, we took a moment to catch our breaths.

"I thought that you were going to kiss me when you got that close to me, that's why I closed my eyes." I said with a giggle. Shawn threw his head back with laughter.

"Yeah but we ended up kissing anyways so it worked out pretty well." Shawn said and I laughed. I kissed his cheek and then looked at him. I brought my hand to his cheek and rubbed it with my thumb.

"Are you tired baby? Do you want to go nap?" I asked. Shawn nodded.

"Yeah, I've missed holding you in my arms while we sleep." Shawn said and I smiled. I then let out another squeal when he lifted me up and carried me upstairs. We cuddled up to each other.

"Your arms make me feel so safe baby. Your arms are my home." I said. Shawn kissed the top of my head.

"Well my darling, you can always come home to them." He said. I smiled.

"I'm so happy that you liked the letter." I said.

"I didn't like it darling, I loved it. Did you get any sleep after you finished writing the letter?" Shawn said and asked. I looked up at him and shook my head.

"No. I was just so excited for you to come home." I said. His eyes widened and he slung his leg over my hip so I was trapped in his embrace - not that I would ever want to get out of it.

"Close your eyes and rest my love. I'm home now. I'll be here when you wake up." Shawn said. I nodded and cuddled my face into his chest.

"I love you." I said. Shawn began to rub my back and I closed my eyes at the soothing feeling - and my tiredness.

"I love you too. Sleep well my love." He said. I smiled and fell asleep feeling happy, safe, and content in the embrace of the arms that I love as he soothingly rubbed my back. I love Shawn so much.
