physical touch. The one thing Tomura can't have due to his quirk. It makes his skin crawl. One small rub against his skin and it's on fire. He can't take it. Which causes him to crave it. His body became so touch starved he started to imagine what it was like to be touched by an actual human and not just the hands on his body. But his violent outbursts dominated his desire for kindness. You are kind. He liked that. He'd use you for it. Guilt you into touching him. You will be his toy.
