A wolf pup separated from his parents before his name was even given gets saved by Heedo, a hare who was passing by.
"Can't you give me a name, Hyung...?"
As the clear and bright eyes of the wolf pup plead with him, Heedo names the pup Wooyeon.
And with that, Wooyeon and Heedo grow up in each others' company.
On the day Wooyeon successfully takes on his human form for the first time upon becoming an adult, a strangely dangerous look flashes from his eyes...
What will happen between Heedo the hare and his natural enemy Wooyeon the wolf?
