Why does the little K of Korean men's team DAY6 speak English so well?

Yongyong is a Korean. He studied in Toronto, Canada for four years, so he is fluent in English. In 2009, when I was studying in York Mills Middle School, I used my English name Brian Kang and my friends to form two music groups, KMESS and 3rd Degrees. Among them, the 3rd Degrees, a trio composed of Terry He (Terry He) and Don Lee, is active, and has released many cover films and songs "Day Dreaming" and "Nothing" on YouTube. On 20 10, Yong Yi was selected by JYP Entertainment and returned to Korea as a trainee.
