Why Why Love (Chinese: 換換愛; pinyin: Huan Huan Ai) is a 2007 Taiwanese Drama starring Rainie Yang, Mike He and Kingone Wang. Since all 3 starred in the 2005 China Television drama Devil Beside You, this was originally thought to be the sequel. However, Why Why Love is not the sequel and has a distinctly different story line. It was originally titled Exchange Love. It was produced by Comic Ritz International Production (可米瑞智國際藝能有限公司) and directed by Lin He Long (林合隆).

The series was broadcast on free-to-air Chinese Television System (CTS) (華視) from 3 June 2007 to 9 September 2007, every Sunday at 21:30 and cable TV Gala Television (GTV) Variety Show/CH 28 (八大綜合台) from 9 June 2007 to 15 September 2007, every Saturday at 21:00.
