Areul Humchida

Hae-Jo is a hybrid of a poisonous bird, the Jimsae. Due to an unfortunate accident caused by his poisonous feathers, he was banished to the human world and is only allowed to return to the divine realm during his mating season. However, because he is a hybrid of a poisonous bird, no one will mate with him, leaving him a lifelong bachelor and a virgin. Hearing that hybrids have lifespans as short as humans', Hae-Jo gives up on mating and attempts to steal an egg. However, failing to steal even that properly, he is about to give up when he discovers something that looks like an egg…! But it was not an egg; it was the sealed power of the Wolf King. The King's power belongs to the King. To reclaim the power Hae-Jo has swallowed, some radical wolves insist that he must be killed immediately. However, Hae-Jo makes a bold declaration that he will return the King's power through 'sleeping together'…!
