Like every woman, LO is very particular about her image. She often boosts her beauty in front of KATE and this time, it is about skin whiteness. Maybe she has the most young and delicate skin in the family before SO arrives; therefore, she is so jealous about SO. YUI scares LO so much and always becomes a target of FU to make fun of. One day, YUI meets SO in the street and bet on the lottery together. But LO misunderstands that YUI tends to have an affair with SO instead.
