One Side of the Water is a 1988 Taiwanese television drama series produced by Ping Hsin-tao, based on the 1975 film The Unforgettable Character and its associated 1976 novel, both written by his wife Chiung Yao.

The series stars Chiung Yao regulars Chin Han (who portrayed a different character in the 1975 film) and Leanne Liu in the leading roles.

In fact Chu Shih-yao has never loved Tso Chiao-jou romantically, rather he treats her like a younger sister, because the Chus and Tsos have been close for several decades.

Given Tso Chiao-jou's severe injury, Tu Hsiao-shuang and Chu Shih-yao both realize their romance is forbidden, so Tu Hsiao-shuang marries the aspiring writer Lu Yu-wen while Chu Shih-yao marries the aphasic Tso Chiao-jou.

Lee Pi-hua actually appears as herself in episodes 19–21 singing Track 3, which was the theme song of The Unforgettable Character (in the film it was sung by Chiang Lei and Frankie Kao respectively).
