Thanks! Yeah, I think so too. They really do like doing it in public. Iwaki tries to hide it, but he never denies Katou when he suggests it. There is a point where Iwaki actually takes the initiative, you might not have reached that point, so I'll say no more.
Mochimune is so strange. I think he's on the verge of being insane, he is a bit psychotic. Interesting character to explore.
