A new story popped in my mind and I am having a hard time to choose the right kpop artist that suits the character's image. Please comment your suggestion for the two characters. It'll be a big help for me. And please indicate from what country you're from, I need it on my next fanfic. :)

Character1: an arrogant boy who doesn't talk too much and who is genuis.
Character2: a cute boy who is kind and gentle.

I also need the kpop group you like.

Example:
B.A.P
Character1: Yongguk
Character2: Zelo
South Korea
