[mikazuki moves to stand up then, hands on knees to steady himself before he realizes that he... does not need to do that. hm. but he will offer tsuru his phone back, even as he hums thoughtfully]

You might owe me something in return, I'm afraid...

We're opening a new gallery in the museum tomorrow evening. Will you accompany me?

[maybe jiji is trying to spoil tsuru twice over]
