S1, E1: During Myongmoon\u2019s Elementary School\u2019s 40th Anniversary Charity Party, there is a charity bid going on. Surprisingly, the items that are up for bid are objects that the top students used before graduating the elementary school. The parents act as if such an event is normal and do not hesitate to bid impressive amounts of money. Suddenly, a woman falls into the swimming pool, and blood flows throughout the pool.
