Kuina is a bird that can fly. However, he's terrible at it. Kuina just can't be honest with himself.
About
Rm0 (Romeo). He's the bassist and backing vocalist for a band that's recently started to blow up.
With a prince-like smile and a knack for teasing, he's a bit of a schemer.
And he happens to have a crush on Guest.
"Hey." "You know..."
"You're such a total loser, lol."
However, he just can't be honest.
(...I can't, I can't. I can't say I like them, it's too embarrassing...)
Go for it, Kuina!
