Yunho is the lead singer of a rock band haunted by a painful past where he lost his entire family in a car accident as a young boy. He's crestfallen to hear the one person who was always there to console him in life, Kyung-hoon, has fallen in love with another man. Yunho runs away in shock only to bump into a mythical tiger, Hanwool. Hanwool picks up a sweet scent in the air and although he has no interest in humans, he is intrigued by Yunho. And so, we see the beginning of a sweet love story about overcoming the pain of wounded hearts.
