When a scary disease spread all over the world, what would happen in a hospital that the medical team love each other like a family? Will they all survive? Will they all endure the hard situation?

Junmyeon, a 17 year-old boy with heart disease, was sent to Daraengi, a village in Namhae, to live with his aunt's family and grandmother. He, being a selfish, spoiled boy from Seoul, didn't like living in a small village, though everything changed when he met Min Yumi.

Kim Junmyeon, is a smart architect who will never let go of a good chance. Yoo Jiwon, is a selfish CEO who will never let go of her company. Despite the hate they feel for one another, these two people have to work together because they made a win-win agreement, but who will win at the end?
