what are some important rules k-pop idols have to follow?

(also) does anyone wanna roleplay with me?
i made a mha oc called kita (hes uraraka's cousin)
kita:
-has light pink hair
- has brownish yellow eyes
- quirk: glass control
- hes very shy when meeting new people
- he stays up practicing music and working
- he covers his neck, arms, and eye (lives with mean boy-friend) (uraraka knows about it and is trying to help him escape)
- stays up late practicing music and works alot
