He's a yandere

Izuku..was into you. He was such a kind boy with full love with you, even those he got easily jealous. You shrugged it off.

But some months later..you heard small scream in alleyway. You went there and saw..

Izuku holding a corpse. His hands were in blood and so was his uniform. He looked at you and his eyes widened.

"Love..no.. What are you doing here?.." Izuku asked, he didn't want you to hate him. He loved you so much, he was over heels for you.
