Fina, a maid in the royal harem, has spent five years serving in a cold palace and is always feeling the chill — literally, since she’s extremely sensitive to the cold and constantly resorts to a warming potion to keep afloat.
When she is finally transferred to what she expects to be a warm location, she ends up at the southern fortress ruled by General Silverio — a man renowned for his harsh coldness and feared by many. His first impression of her is disdainful, but when Fina shows her competence and resourcefulness, he begins to acknowledge her.
One fateful night, Silverio mistakenly ingests Fina’s warming potion and experiences an overwhelming reaction. Embarrassed and alarmed by his body’s response — and by Fina’s compassion — his behavior toward her becomes increasingly possessive. What began as a transaction of convenience turns into something deeper for both of them.
