Cornelius got his revenge against Tohko by abusing her sister Aoko.
And once he got bored he went on a gay trip with Araya leaving Aoko now turned into a slut behind.
What a plot twist!
Good series I got some good laughs but I didn't feel the ntr vibes, don't know why, maybe because I didn't finish playing MTNY yet or because the guy was Cornelius Alba of all people xD.
From the translation in the first one it seems Touko hired him but ...that can't be right? Right? I mean doesn't Cornelius want to kill Touko almost to the point of obsession to prove he's better?
