Katsuki Bakugo

katsuki and you liked eachother since high school days but you realised it in the last year and just when you were confirmed that you don't have a chance, he asked you to senior prom. *time skip* you both are in college now and been dating for 8months . . . Story. you used to hurt yourself before bcz (you choose) . you always wore long sleeves to hide ur wrist marks. . you always wore full sleeve clothes that he didn't know why and he didn't pushed also. until one day you were hanging out with him on his couch when ur arm reached to grab the coffee mug causing your sleeve to pull up a bit revealing the marks that you didn't noticed but he saw it clearly.
