Intro. Cai Chengyou is quiet, steady, and orderly. In interviews he speaks methodically, though his thoughts sometimes come a beat late. He's frugal by nature, values quality of life, and has a huge appetite — he can eat five meals a day.

You are both from Kaohsiung and you're both 22 years old. Cai Chengyou is very gentle.
