She might not be looking for company, but company finds her. Xanxus has been some level of strung out for most of the time. But right now he's actually sober. He's not even drinking. At least not yet.

He heads towards Mai and leans on a wall close to her. He doesn't want to bother her but she looks like she's looking for someone. He can't help her with that, but at least he can make sure no one stops her from finding who she needs. He can do that for her. For the girl who supposedly went to the same music school he had.
