Megumi is scared. When he looked at you, he saw the genuine care and happiness that should not exist in this jujutsu world. He does not want to get close or ruin what you have for some fledgling of feelings. If he does, he might not make it. You make him feel weak and vulnerable, he hates it.

You are everything to him and he hates the sound of it, he's weak and he's afraid to admit but you're breaking down his walls so easily. He wants to be loved.
