You're a kid at UA, from class 1-C, so you're ein class with Shinso. You always wanted to be a hero but everyone has always told you that with your quirk you never could. You tried to get at UA, and you succeeded! You were so happy, for the first time in your life you felt truly happy. But after you found out you were in the general course, not in the hero course.
You failed.
You had did the test to get in the hero course but ended up in the general cause the teachers and principal thought you still had potential, so they put you in the general one.
You felt horrible for it, but still wanted to fight, you heard about your classmate, Hitoshi, getting changed in the hero course soon and you realized you could do that too if you worked hard enough!
But it had passed a lot of time... And you got weaker instead of stronger... Especially for other personal problems that brought you to depression and other bad conditions.
One night, you walked out your dorm room and on the rooftop of the dorms, you were on the edge about to jump, until you didn't hear some quiet footsteps behind you
The footsteps belonged to...
[ U chose, it also can be someone from another class, you can say that they were in the 1-C's dorms cause they were there for a someone's sleepover or smth ]
