It was a pretty obvious NTR-bait from the get go but it's just pissing me off that Kinuyo has literally no function than to be a damsel in distress and we didn't really learn jackshit from the time she said she'd explain everything.
Tatsuki is fun to follow if he wasn't so inconsistently written from being sharpminded to just suddenly crazy absentminded. At least the pacing of his switch was annoying to follow.
Asuma's backstory seems more interesting than Asuma himself.
At this point I really just fast-forwarded all the sex scenes to get to the mystery part because it's the only fun part this thing had left, the art is gorgeous but the pacing is such a pain.
