I'm underage 1989

Cindy (played by Cheng Wenya) completed her further studies in the United States, returned to Hong Kong, and worked as an instructor in a juvenile correctional center. Yuan Heping (played by Yuan Jieying), Luo Miner (played by Li Lizhen), Chen Aqin (played by Irene Wan) and Wu Nao (played by Carina Chan) are the four female prisoners under her. Although these underage girls appear innocent and lovely on the surface, they actually have complex and bizarre life experiences. By chance, Luo Min'er fell in love with kayaking coach David. This relationship was strongly opposed by both families. Cindy intervened and fully respected the free will of Luo Min'er and David, which eventually led to a relationship. After that, Cindy solved the long-standing misunderstandings and conflicts between Chen Aqin and her father through persuasive guidance. What Cindy didn't expect was that Yuan Heping turned out to be her half-sister, and she caused a series of troubles for herself in order to help Wu Nao, who was heavily in debt.
