4) How vain is your character? Do they find themselves attractive?
Hongki knows he is attractive, but he is not vain about it. He knows that women, and occasionally men, find him attractive, and he is not afraid to use that to his advantage. He takes good care of his appearance and always making sure he looks his best before leaving the house.
He does, also, find himself attractive, but again, he is not vain about it. He simply acknowledges it as a fact.
