[Guarantee drinking] is a drinking party where you can get money as a reward for coming to the drinking party. Entrepreneurs and managers in the Nishi-Azabu and Roppongi neighborhoods invite young girls to pay their fees, and this is a part-time job that has become popular among female college students. This time, Koko-chan, a naive busty female college student from the countryside, participated in the gala drinking for the first time. If you join a rich drinking party for 2-3 hours, you can get a large amount of money... that kind of world isn't easy, is it? (laughs)
