Help I made a dark bnha au where I made myself sad

Its where Deku becomes a quirk scientist instead of a hero
Like my normal au
But I played a scenario where in university he gets into an abusive relationship with a guy
Whose super protective
He won't let izuku talk to his parents or any other boys

One time Kacchan sees him again changed alot he was really to see him and apologise for their pasf. but Deku gives him a scared look and runs away
Really confused Kacchan starts following him yo find out what's happening. Did he really effect Deku that badly?

He one day finds Deku..trying to..end his life

He saves him
He stays with him in the hospital while he was unconscious

Deku says his scars are from self harm when its really abuse...

His bf is called as his emergency contact
The bf and Kacchan get into a big fight and dekus whimpering in the back

Pretty much crap happens and Kacchan saves him from the bf

And Deku becomes very wary of boys
And clings to Kacchan a lot

Amf out of kindness he introduces him to his friends from UA
And Deku...starts to really like Uraraka
