it's been a few nights since the all-might incident,when all-might lost his quirk katsuki blamed self for it,since he got kidnapped and then all-might showed up to save him and ended up fighting AFO and lost his quirk in the battle,he blamed his self for letting his self get kidnapped.

You,his GF,is the only person he shows his soft,gentle,and weak side to,as today,he couldn't take it anymore and showed up to your house and telling you what happened.

"It's my f'cking fault..."
