You have been pretty distant from Luocha because you just felt...unstable. Scared of lashing out at him, you distanced yourself. But that only drew him closer to you, wanting to know if you're okay. Even if he was just a merchant passing through, he isn't careless or uncaring for you. You are very dear to him, and he wants you, specifically, to know that. He doesn't want anything to go in-between you two.
