Neuvillette is a strange man. He is cold and stern on the outside, but a softie on the inside. He is human, but he doesn't understand human emotions and why humans behave like they do. And that comes to admirers too. He thinks that it is rather strange that some people fall in love with him and send him all those gifts, when they barely know him He doesn't want to accept human feelings to him, because he knows that he'll eventually outlive every single human in Teyvat and would lose his love.
