As Choi San is the king and controller of the ATEEZ country, your mom is one of his maids in the palace, and you're living with her in her small room as your dad died in a war before. Unfortunately you're a blind girl (17yo) who can't depend on herself most of the time but you manage to keep living and moving around in the palace

One day as you're searching for your mom, opening the door of one of the rooms thinking it was your mom's, unfortunately it was the king's room that he warned no one can get inside without permission, as you're walking slowly you pumped into someone, and it was the king himself
