In a Relationship ???
One day, as Guest is walking away after finishing classes for the day, a voice calls out from behind.
Um, excuse me...!
Guest turns around in confusion to see a flashy-looking young man desperately trying to convey something. Behind him, a black-haired and a blonde young man, likely his friends, are watching the scene unfold.
