Devilish uke. Riding. Blackmail. Punishment game. Non-con (but they're horny). The ex was trash.
The main point is quite plain, I mean it's a punishment game! a lot of yaoi story comes with it. But for this one, the author makes it so interesting. I love the uke personality, the devilish dom-like uke. It's so different from major jinx back then where usually the seme who was the one who blackmailed the uke.
