Itsuki, a senior high school student, was ordered by his mother to work as a servant under the Tenmei family during his last summer break. Little does he know that he is actually one of the bridal candidates of Tenmei's young master named Jin. Competition proves to be fierce as the contenders are all male Omega from well known families, while Itsuki is only from an ordinary household.

Kusaka Taisei was born into a good family without knowing much about the world. He became interested in the reserved and tranquil beauty of the transfer student, Mizutani Aoi. On a day off from school, Kusaka spotted Mizutani going somewhere, and he succumbed to his urge to trail behind him. Kusaka arrived to see a sex parlor in front of him. It was inside there that he encountered Mizutani and was invited into a private room. In exchange for keeping quiet, Kusaka was given a blowjob.
