Oh boy it's juice and jam time. Honestly I am both surprised and not that Kanako would be the one to screw the pooch in some way. Despite her coming across as the mature one of the group, she is just as impulsive when it comes to Ueno and prolly the hardest to read sometimes. I wonder exactly how this is gonna go down, will she apologize and try to smooth things over, will she assume Ueno is no good for Moka and own up to what happened possibly outing him as a masochist, this has been the most exciting chapter since the two started dating. I know Chiskaki is suppose to be the main bully, but I can't help but feel the author is working his kinks out with Kanako in alot of ways because the series seems more interesting when she is involved (or I am just a pervert lol)
As far as the back and forth going on here, let's calm it down guys. I do agree the comparison to Prison School is an odd one, but I can also see where it can be interpreted that neither is really that interested and one is basically using the other to help get past their previous trauma.
I always wondered if it's because both are subs, and are not use to not taking the initiative, but it's clear if both want to make it work they need to find a way to see each other as beyond just wanting to break their programming. I do think both LIKE each other platonically atleast. But their romance does seem rushed and we never seen their sexual chemistry really explored, which makes me think back to what Riku said about his chemistry with Moka. That could have been a forshadowing of how difficult or doomed this relationship between Ueno and Moka could be.
