estar's manga / #Single parent(5)

there r few things i just don't get, how can a hetrosexual, and at that a very sexually promiscuous male suddenly be ok, not only with sex with a man but being the bottom?!? just doesn't compute. what's more don't get why we have the child (Chii), that is mostly or rather conveniently absent all the time, unless she's needed to further the plot, and again why can't she be his kid?!? why is it important to point out that he isnt her biological father? this was cute and ok, but i think the character i liked the most and would like to know and see more from is Ryou-Mei...

cH 264 (stopped halfway though) this was going fine (even though the main plot was over & done with IMHO - but then we get this twisted gross sibling love sh*t pushed at us between Ai & his older doctor sibling & everyone is calling it natural b.s - sorry nope!
