The Sea of Swirling Frost

As punishment for his crime of harming humans, Gumiho(1) 'Seori' is exiled to live alone on an island called Gokdo.

Until one day, Parang, Yongsung(2) Kingdom's Crown Prince, washes up on the island with a deep wound. Swayed by his warm affection, Seori shares his body and heart.

However, in order to capture the tiger demon 'Muryung', the one that plunged the kingdom into chaos, Parang has to make use of Seori, Muryung's adopted son-

"All I have is this impressive body, so will you still take me?"
