Man, there's nothing worse than hanging out with your bro, only to find out that he is actually a hot chick who want to bang you. Shame on you, catfish, shaaaaaame.

But NGL, an adult talking about inappropriate stuff with a minor (whether it is a boy or a girl) reminds me of certain sunglass-wearing doctor and a certain person with a surname that sounds like bison.
Y'know, normally I would point out that Shigure should just stop the dumb "sending I like you vibes" thing and just tell the guy directly. However, Kotarou is such a dense neutron star of a simp he wouldn't even get it if she told him in her best bedroom voice that she wants to fuck him.
