On the surface, Zen is known for being a very eccentric and flirtatious character. He will often talk about his looks, praising and complimenting himself for how attractive he his, as well as how talented he is when it comes to singing and acting. Zen tends to compare others to himself when it comes to looks, frequently telling Yoosung to work out to look half as good as he does. However he is very loyal and caring, especially to those he cares about.

Note: Be flirty but not too flirty to the point it sounds weird
