UGHHHH MY HEART< it seems it was when he was off-guard but OMG :'(
At least her first (?) kiss was was Ren? /Corn???
What the!!! Damn! Who's the bitch?!! Hope she's not some new rival of kyoko. If she is, she not gonna win.
Honestly that first kiss too was kind of unnecessary. Like sensei made do with ren's see if explanation but c'mon. We all know shou stole it. Even if we don't wna acknowledge it. Her first consensual kiss? That was corn. But her first kiss ever? That was shou. The bastard.
