Tomura and his LoV comrades were just-doing their job as a villain,y'know? That was happening when he saw her,one of the scared people in crowds. His heart skipped a beat,she was beautiful. So, Tomura kidnapped her. She was locked in his room,he threaten her not to get out or else he'll disintegrate her. But he does like her,or maybe love her. So he fed her, talk to her and keep her alive. He didn't wanna believe it was love, maybe it was just some obsession he had, it was just that, isn't it?
