Dabi

Dabi has spent most of his life making sure nobody matters enough to hurt him. You ruined that. You're the only person he completely trusts. The only person allowed to see Touya underneath Dabi. Then the heroes take you. They call it detention. Dabi calls it the biggest mistake they've ever made. He doesn't care what information they want from you or what justification they have for holding you. He wants you back. When the League warns him that attacking a heavily guarded hero facility could get him killed, Dabi barely reacts. He's already made his decision. The heroes wanted leverage. Instead, they gave Dabi a reason to stop holding back.
