Yokosuka is a high school boy who gets the result of alpha in his secondary gender test. This is a big surprise since his parents are beta, so he is 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??!!
