Deku's POV
She walked away, she just walked away leaving me. I looked down at the ground. 'She loved me?' I thought to myself. I'm so stupid. Now that I think of it, she was always around me, she always helped me and made me smile, and she hugged me any chance she got. I feel bad now. I didn't realize it sooner. She suffered, she was in pain, all because of me. I walked back to the cafeteria and seen she was talking to Iida like nothing happened. 'Does she just not care anymore?' I thought as I sat down. Usually (y/n) would hug me went I say down, but she paid no mind to me. I looked down, sad that she doesn't care anymore. I felt arms wrap around me I looked up expecting (y/n). It was Uraraka. I hugged her back and kissed her head. I tapped (y/n)'s shoulder and she turned to me. "Shares my hug?" I asked quietly. "Oh do you want one?" She asked. 'What the heck? Is she forgetting everything?' I thought as I shook my head yes. (Y/n) hugged me but it was an awkward hug, the type of hug you would give someone that you don't really know. She let go of me and turned back to Iida.
Time skip
It's been a week now. I never get hugs, she doesn't talk to me unless I say something first, and she just stopped being with me. It's like she isn't my friend anymore. I feel hurt, I want her back. I miss her hugs everyday, I miss the stupid conversations we would have and I miss her. I felt a small cough comming. It got worse, a single petal fell out of my mouth and I looked at it in horror. 'I have hanahaki.' I thought. I can't love (y/n), I have a girlfriend. I need to get rid of this, it's wrong.
I got the surgery yesterday. I feel so different. I don't try to talk to (y/n) anymore and she doesn't talk to me. I love Uraraka and I'm still with her. (Y/n) and I just drifted apart. We never spoke and we didn't even say hi to each other. It kinda hurts that I lost one of my best friends, but I'm happy with Uraraka. (Y/n) hangs out with the Bakusquad now. She got really close to Kirishima and Mina.
Month later
(Y/n) ad I haven't even made eye contact. She is with Kirishima now and I'm still with Uraraka. She looks happy and I'm happy to. I guess we just weren't made to be together forever.
I was sitting in class and I opened one of my journals to the back. I seen a note. It said, 'hey bestie. I love you, I can't wait to be a hero with you. We will always be together no matter what! Love you Deku. ~(y/n)~' I reread the note and looked at (y/n)'s back. I ripped out the note and threw it away. 'I don't need that.' I thought as I sat back down. From that day (y/n) and I never spoke to each other again. And eventually I never seen her again. I just have memories of her.Someone requested a part 2. I may have or may not have cried a little. Hope you like the part two.💕
