At this point I feel the mangaka is either just giving us the finger with this horrid development or creating the catalyst that makes Ayumi and kotaro communicate better about issues.
But seeing how in the last conflict where kotaro wasn't truthful about why he would've stayed with his brothers had the little one not spoken up, this will not end any differently. Conflict resolution will shoot out the ass and Ayumi and kotaro will have hot make up sex.
It was good the first two times but now this is going too far. Besides seeing Ayumi get riled up, I don't see what other purpose this serves but to create useless drama without consequences.
I'd go more for the first option: giving us the finger !!! yeah the middle one ╮(￣▽￣)╭
Because why not, right? LOL
Lmao is this guy a siscon?
