He's a good person.

[Despite being something of a pervert. Yukiko can see why people would like him that way, even if she herself doesn't. And it's not like Mami didn't say it before, that people from Citadel have some things in common.]

And I can't really disagree. It's nice having someone to talk to who's got some manners and charm. [Which Mami certainly does have.]

Goodness, I'm excited for both of you.
