"HEY HOW DID YOUR PRIVATE TIME WITH BAKUGOU GO?!?!?" Huh..? M-MINA!? And the whole class.. great! "M-mina?!? Did you tell everyone?! Why is everyone looking at me?!??" Mina laughed and said "told everyone what??" They started getting closer and closer "yeah told us what Y/n?" They said in choir. "T-t-that m-me a-and-" suddenly i heard someone screaming "WHY ARE YOU IDIOTS STANDING AROUND MY GIRLFRIEND MOVE SHE'S MINE!!" Kacchan..!? Why did he have to say it out loud..?!? "GIRLFRIEND!?" I could feel my face getting red and I crumbled up to the ground "yeah girlfriend and she's mine so back off" he pushed them away "girlfriend huh! Bro it took you long enough" said Kirishima while punching Kacchan's shoulder. "Shut up shitty hair.." Kacchan put his hand in front of his face to hide his blush. "Lets go Y/n.." he said while helping me get up. "Kacchan why did you have to say it out loudddd" i whined while i got up "because i want them to know you are mine" he whispered in my ear. "Hey what's with Midoriya? He looks pale.." this whole time Midoriya was just standing there. He wasn't smiling as usual.. he looked sad.. he was just staring at his feet.. i felt heartbroken when i saw him like that.. "what do you mean he looks normal?" Kacchan said but i knew that he knew something was wrong. I walked over to Midoriya and put my hand on his shoulder. He ignored me. "Hey are you alright??" He kept looking at his feet "Midoriya? Look at me!" Suddenly i saw tears falling to the ground.. he's crying.. "Midoriya stop ignoring me what's wrong? Please tell me.." "why did you have to do that.." he said as he walked away not making eye contact. "Do what?! Midoriya!!" I stood there not knowing what just happened but i could see Kacchan looking at me as if he knew wgat was wrong with Midoriya.. "Y/n lets just go okay.." Kacchan said. I nod. He held my hand all the way. He held it tightly as if he was scared of letting go. "Hey where are we going? This not not the way to my dorm or yours" he smirked and said "that's because we are not going to our dorms. I want to show you something.." show me something? We kept walking until there was like this playground. It was surrounded by flowers. "Why did you bring me here?" He looked kinda disappointed but he was smiling. "You don't remember?" What am I supposed to remember about this place?.. it looks familiar but i don't recognise it.. "i don't know.. it looks so familiar but.. i don't know?" We walked around with me "try looking at this tree. Does it say anything to you?" I looked at the tree and walked around it. Y/n and Bakugou "H-huh..?" That was carved into the tree with a heart shape. "I remember this!!" He smiled "It was the day we first met.." he sighed "yeah.."
flashback
"But mommy!! I don't want to go play with them! What if they dont like me.." Bakugou's mom patted his head "it's okay i'll be back in a few minutes just go play with them! See that girl is also playing on her own! Go say hi to her!" Bakugou sighed "but mooom-" she kissed his cheek and said "I'm sorry Katsuki but i really have to go!! Don't go anywhere okay!" He nod. He walked around the playground watching the other kids play. He walked up to the little girl who his mom was talking about and sat next to her "hi" she said while smiling Bakugou smiled back and said hello back. They started talking and He found out her name was Y/n and lives next to his house. "Hey Bakugou! I wanna go to the swing! Can you push me?" She said as she ran to the swing moving her legs. "Okay but after that you have to push me too okay!" She nodded and Bakugou pushed the little girl. After a while Bakugou's mom came back and she told him they had to leave. "But mom me and Y/n were just playing!!" Bakugou said as he held her hand tightly "I don't want to go yet!!" Y/n hugged him and said "it's okay! We can play tomorrow again!" He smiled and said "okay but let me do something first.." his mom and Y/n looked at him as he took a a sharp stick and carved Y/n and Bakugou into a tree. he walked back and said "okay lets go" the two children waved at each other as he waled away with his mom.

He hugged me tightly and kissed my cheek. "You were my first friend.. and now my first girlfriend" he said grinning "as much as i like spending time with you, we must go back to our dorms before they notice we're gone shall we?" He said as he bow down, grabbed my hand and kissed it. Gosh.. what a gentleman hehe.. i giggled "okay mr. Bakugou" we walked to our dorm and I noticed he was going the sane direction "hey your dorm is the other way you know.." he grinned "who says I'm sleeping at my dorm?" He says as he winked at me "im sleeping with my girlfriend today" he smiled like crazy " hmm that's fine by me but you're sleeping on the floor!" I said. He did a sad face and whined "but i wanna sleep with youuuuu~" "no" he looked at me with puppy eyes "pleaaaaaase y/n? Or no more kisses!" I dramatically put my hand on my mouth "nooooooo okayyy you can sleep with me!! I cannot live without kisses!!" He grinned "yaaaay!" We were at my dorm and he jumped on my bed aggressively sniffing my pillow "ahh~" i laughed and threw a plushie at him "what the heck" i said through my laughs. "It smells so gOOOOOD" i laughed and I cuddled myself next to him "night Kacchan" i said closing the light "good night Y/n" he softly kissed my forehead.
