"I've got absolutely no interest in your nakedness." Coming from the previously so kind and gentle manager, those are the cold words that won't leave her head. In order to get over her one-sided crush, Yuu travels by herself to stay at a gorgeous hotel she found. After arriving at the bus stop, she is greeted by the gorgeous manager who says he has come to pick her up and bring her to the hotel. She is so taken in by his beauty, that she doesn't hear a word of the explanation of the hotels services and signs the contract with no cares at all. That night, the staff member in charge of her room barges in and pushes her down on the bed, telling her that she will fall in love with him. He lays kisses upon her collarbone, her chest… and as his tongue goes lower and lower on her body she begins to feel things that she's never felt before and that set her body on fire.
