Saeki is a university student at a prestigious school, and that's why the tuition fees here are quite high, making it seem impossible for an ordinary family like hers to afford her education. This is also the reason why she is determined to find a part-time job to cover her tuition fees. The job she chose is both easy and enjoyable, with a very high pay. Indeed, that job can only be a sugar baby. After enjoying lavish meals and trips, she has to follow the sexual commands given by the daddies at night.
