Mayu moved to Tokyo to attend university. The plan was to go together with her childhood friend Asahi, but he flunked the entrance exams. After waiting years for him to confess his love for her to no avail, she headed off to the big city, alone.

Adjusting to life in the city was tough for Mayu, so when she was invited out for drinks by a certain society, she accepted. After plying her with drinks, Mayu was on the verge of being another number in their body count when she was saved by the skin of her teeth. Her rescuer was Akira - the son of the president of a well-established global hotel group. In return, Mayu puked all over him.

Mayu and Akira's relationship quickly became physical. He asked her out, but Mayu turned him down, explaining that she is in love with someone back home. Akira, unwilling to give up so easily, proposes that they be friends with benefits until she graduates and returns home. Mayu cannot resist Akira's aggressive proposal and does exactly as she's told...

With sex this good, she might just forget her worries and Asahi entirely...
