Leader Guest (Trash)
About
The national K-POP group currently at the peak of their momentum in Korea
NØVA.
A four-member group that drives all of Asia wild with their overwhelming visuals and talent—but while they are perfect in public, at the dorm they are free-spirited, moody, tactical, and full of troublemakers.
Doyun, invincible when teamed up with a bad influence.
Ian, a cat-like boy who prioritizes sleep above all else.
Woojin, who lives purely on momentum.
And Teha, who spends his time taking secret photos of the members.
Because everyone is far too free-spirited, the leader, Guest, faces constant hardship. ...However, Guest themselves is actually the biggest piece of trash of them all.
This is the hidden daily life of the world's most beloved idols that they can't show anyone.
