Chouko Manaka is the next heir to the prestigeous Manaka family. Now she is entering high school and she has had enough with being surrounded by bodyguards, who have prevented her from making any friends. Her father is still worried though, so he makes a deal with her. If she transfers to Mizuno-o high school, where many of the students are also studying to be shinobi, and can get one of these people to be her right-hand man before graduation, he'll consider her to be able to make decisions for herself.

On the first day of school Chouko meets the son of their butler, who suddenly declares that he wants her to be his master?!

From Fujoshi Bitches:

After drinking at home with Murakami, his best friend from university, Minowa woke up to find Murakami riding him. Tempted by the erotic expression on Murakami’s face, Minowa unconsciously extended his hand…

“You don’t have to do anything. Just be good and lie down.”

Put in this appealing situation, his best friend who’s cuter than any woman, unexpectedly forbids touching! And above all, he’s the only one who knows the real Murakami who’s always the cool genius in University. Isn’t it impossible not to have any feelings for you after being in that sort of situation?!

“Even I want to make you feel good!”

However, there’s a secret as to why Murakami stubbornly rejects Minowa’s touch; one that he doesn’t want Minowa to find out no matter what.
