Water-Logged (MHA fanfic) (T/W)

"Inko, honey! I need you to slow down," Katsuki stomped through his home and saw his mother on the phone with his aunt. He couldn't hear most of what was said, and only began to worry as his mother quietly said, "wait... Izuku? He- he did what?"

Or;

Katsuki Bakugo tells his childhood... friend...? to kill himself, and he does. His whole life takes a turn when he realises that he wasn't the only contributor to Midoriya's suffering, and holds a serious grudge against All Might.
