The main character is Jotaro Jigen, he is described as a hardcore, no nonsense, almost toxic masculine, a leader of the school council in the all boy school. He happened to save a girl from some thugs and that girl then came to his house, decided to return the favor by offering herself.

The "girl" is Sakuramaru, actually a boy kabuki actor, who specializes in "female role" (called Onnagata), he vowed to stay by Jotaro to enhance his female side or whatever, and clearly, he has a crush on Jotaro.

Of course, the hardcore Jotaro rejected Sakuramaru right away, I mean, Sakuramaru is everything Jotaro hates in a man: he wears female clothes and underwears, long silky hair, chatty, cannot do housework, almost always messes things up. It's the good old No Guy Wants to Be Chased trope, Sakuramaru proclaims to be Jotaro's lover, keeps trying to get closer to Jotaro, calling him Jo-sama, darling, ect.

Jotaro, of course, is annoyed by him and keeps trying to push him away, beats him up (in a comedic manner of course) but somehow Sakuramaru gets permission to stay in his home lol. He then keeps getting roped in a lot of things with Sakuramaru and the bizarre events around him. Despite saying he hates Sakuramaru, whenever the latter gets into trouble, Jotaro will immediately get worried and try his best to rescue him lol.

But yep, at the very last page, it is strongly hinted that Jotaro is getting softer for Sakuramaru, so eventually, I think they will get together lol.
