A Hainanese meets a Teochew girl. One is a girl with a masculine appearance and the other is a boy with a feminine appearance. They live in the same building. They were originally unrelated, but they became enemies because of a bra that fell from the sky. He took the bra as a talisman and took it for himself. She posted "bra-seeking notices" everywhere and searched hard. The battle for underwear is about to start. She thought that the past grudges were resolved and fate had come to her, but her old love Meihui suddenly came. The room was a triangle of two sexes, and hugging was too crowded. His brother, the ghost, also joined the battle and influenced the overall situation of the relationship. Singapore's new director shot an unusual romantic comedy with a low budget, with non-professional actors as the protagonists, confusing gender stereotypes. It is not a handsome man or a beautiful woman, but it is still sweet.
