She loves him like family, to put it extremely simply. Goroh isn't quite a brother, but that's probably fairly close to what she considers him -- maybe something like a cousin. In any case, she loves him dearly and would do just about anything for him, but he's very capable of pushing her buttons. Which he seems to enjoy. Which both irritates and amuses her.

Despite everything, though, she's really glad he's here again. And she's glad he was willing to provoke her anger in favor of setting her back to her usual self after the AU effects... even though she's still a little bit miffed that he did. It's a good thing and she knows it, but she still had some blissful freedom from the Boundary for a while there.

But still. Litchi love Goroh. In a familial sense.
