I Should've Known- Suicidal Deku, BakuDeku

Hey guys! This book will have basically EVERYTHING you need- angst, fluff, and some adorable bakudeku moments! I'm open to advice, as I'm a new writer! You guys can comment and request for things to be added! Thanks for reading!

Izuku Midoriya. He was the happiest boy on Earth. Always smiling and laughing, surrounded by friends who cared for him. His mother was the sweetest woman, loving and kind.
All this, of course, ceased to exist when he turned four.
He was declared quirkless.

All his friends crumbled away, and his mom withdrew from him, one bit at a time. Indifferent to her son at first, but slowly, it evolved to verbal threats, and when he was about 6, it had transformed into abuse.
Izuku felt the stress and the sadness building up, a tidal wave pressing him down. How could he let it out? One day, he found a way to let all the stress out. He never went anywhere without a blade again.
Little does Izuku know, that someone has been carefully observing him from the shadows.

Will Bakugou save his soon-to-be-fiancée from himself? Will this King Explosion Murder discover his true feelings for this adorable broccoli before it's too late?

I do not own any characters, these come from My Hero Academia.
Speaking of characters, I was thinking if anyone wanted to be added into the story, simply state your role play name , and what you would look like. Put these comments in the section which says 'Application Zone'. There will be specific roles you can apply to! Please do not apply after the time is up or the role has already been filled!
