Could an ordinary girl be able to change a terrible curse for herself and her kingdom? Merle Celosia is a poor princess from the Kingdom of Demhous who has been cursed since birth. If she comes to a celebration of love like Valentine's day, then she will disappear from her country, be dragged, and sealed to become a prisoner in the land of werewolves. Because of that the family always monitors and forbids the princess from attending such events, but Merle's curiosity makes her one day break the rules since she was a child. This amulet that she always wears around her neck is the only antidote for Merle from being harmed by werewolves, even though she is dragged into the werewolf kingdom. Merle must bear the consequences of her mother's mistake to the werewolf king which at that time caused a great conflict between the two camps in the past. Prince Eldon, the only son of the werewolf king who is always voiced by his father to hate humans, really hates humans, but everything changes when he meets his royal prisoner, Merle. Both feel a chemistry even though they are different. But the conflict that once existed is coming back with its own consequences. Merle and Vorigon are faced with a tough choice, let go or fight for it.
