Even though Pong and Sui do not date anymore, Pong still stays with Sui because he loves her dearly and wants Sui to be happy but she does not realize it. Sui is unhappy about her image and wishes to be someone else. One day, Sui meets an old man in the elevator and through magic her wish gets granted. She can be whoever she wishes to be. It's like a dream come true. Her first wish was to be like Rose, who is a strong working woman and whose lover is Rangsit, a perfect business man by every girls' definition.
