depressed izuku (shindeku)

(i am discontinuing this story since i have no idea what to do, it was only supposed to be a 3 chapter story then finish but i had a couple of ideas so i wrote 2 more chapters and now i dont have any clue for another so im leaving it as is, sorry for this inconvenience, but i hope you liked what i did write)
info-
izuku has some major trauma because of his past, resulting in him being very closed off to his classmates and pretty much everyone he interacts with.
there are only a few people he is really open with, them being.
aizawa (dadzawa)
hizashi (papamic)
shinso (his crush)

izuku still isn't that open about everything to his crush but shinso know enough to help him,
shinso is also izuku's only friend and the only one who ever put in the time and effort to actually brake down izuku's walls and be there for him.
the duo are very close and unknowably to them they both have crushes on eachother.

so what will happen when shinso finds out that izuku is struggling with bullies and said bullies are in the same class as them?

will shinso be able to help izuku stabilize his mental health?

also when nezu decides to host a singing competition between the whole of the third year izuku divided to sing one of the songs he wrote,

what will his crush think?
what will his classmates think?
will he gain more friends?
will his bully's step aside and let izuku be happy?
