Bai Han Qi, Bai Luo Yin's father, accidentally throws Luo Yin's underwear to the drain. Luo Yin then informs his friend Yang Meng that his mother (Jiang Yuan) is getting married. Meanwhile, Gu Hai is conflicted on deciding to whether or not attend his dad's remarriage ceremony and approaches his girlfriend, Jin Lu Lu, for advice. He later has dinner with his dad, Gu Wei Ting, and his future new stepmother Jiang Yuan, but the dinner soon turns sour as the father and son quarrel. Luo Yin ignores his mother when she advises him on his future education, and she is later scolded by Luo Yin, leaving his mum in tears. Gu Hai moves out from his home and seeks his older sister on relocation. Both Gu Hai and Luo Yin report to class but notice that their teacher resembles Jiang Yuan (mother for Luo Yin and stepmother for Gu Hai). Gu Hai was punished by the language teacher for submitting a blank homework assignment, and so, Gu Hai tore Luo Yin's homework out of his workbook as revenge for his unique handwriting which Gu Hai doesn't like. Gu Hai met up with his friends Li Shuo and Zhou Yi Hu.
