A prestigious institution, Sakuradani Academy is like a beautiful, isolated garden, designed to shield the daughters of wealthy families from the corrupt outside world.
The protagonist, Masayoshi Kannari, has been teaching there for about four years.
Though still relatively young, he’s well-liked by both staff and students as a “kind and sincere teacher.”

But in truth, he’s a predator—a lecherous educator who uses his gentle facade and silver tongue to seduce unsuspecting girls.
He finds it all laughable.
At the end of the day, women are all the same. He’s grown jaded by the girls who throw themselves at him without him even trying.

Then, his attention is caught by Yukino Kirihara, a timid and beautiful girl who’s become somewhat isolated in class.
Yukino is different—she’s the “real deal.” Her noble demeanor, respected even by her peers, stirs something in Masayoshi for the first time in a while.

As a teacher, he earnestly listens to Yukino’s concerns, all while sizing her up as his next target.
And Yukino, in turn, begins to develop a faint affection for him…
