Yokosuka, is a high school boy who for the first time gets the result of the alpha gender in his second gender test. Which was a big surprise since his parents are beta, so he was forced to attend the dating party for the marriage interview proposed by the city council. There he meets many cute omega girls but, will he be able to find a nice girlfriend...!? Motivated by this, Yokosuka decides to undergo the compatibility diagnosis and the kind of partner who was on the other side of the door with whom he obtained a maximum percentage of 92% was someone rather gruff with a look of unfriendliness that turned out to be... A MAN!!??

Honda finds a pair of panties one day as he's doing laundry in the company dorm. Turns out they belong to his kouhai, Shibuya. As Honda tries to calm Shibuya down, an awkward exchange about men's underwear ensues and thus begins a series of strange encounters between the two of them.

A story about an excellent and manly salaryman, whose beauty is extraordinary: the senpai Kitagawa-san – and his although dumb but very handsome kouhai, Nakamura-kun. In the middle of the night with a bottle of sake, a very girlish confession is to hover over the poor kouhai Nakamura-kun. Backed up with his very own fantasies and undeniable desires, he jumps his sempai Kitagawa-san… unexpectedly though, Kitagawa-san doesn't have anything against it!
