Echoing kidoraku's comment on the dryness of the romance and stiffness of the characters. There's not much chemistry between the main couple aside from the sex scenes, which are hot and pretty well drawn but with not that much emotional connection behind them.

There's barely any tension from outside the relationship, despite the interesting premise with the families and powers. Everything gets solved neatly with a little bow on top, the families are both super accepting of everything after a session of talk no jutsu, and the couple don't even suffer negative consequences for going against tradition. The art is mediocre: not ugly but not good either, with heads occasionally looking a bit wonky.

I'm disappointed beyond imagination. The premise is very good but the execution is terrible. Characters are stiff and the whole romance is dry as an old rusk. No matter how you look at it, there are no signs of love or affection between the characters. The whole romance feels forced. There wasn't a single sparkle between so-called lovers.

I think that mangaka was trying to make the younger guy, Nagi-kun, a shy and cute boy but he failed. In reality Nagi was terribly dull and emotionally retarded, I mean his actions were so immature it hurt and after that, when they decided to have sex this boy started screaming out of the blue "Ah! your cock!" that it left bad taste in my mouth. I didn't have fun, I won't recommend this work.
