A serial killer murders a girl from his neighborhood. The residents begin to suspect him one by one, as he tries to cover his tracks and plans another kill before escape.

When his wife is murdered, Dong-ho loses the light in his life, breaks down and falls into depression. But he knows that as long as the killer is still around, he can not get out of his loss. Then, one day, he receives a call and can not believe who he is listening to.

After losing his family when he was young, Nam-soon feels no pain. He cannot feel physical pain and is emotionally barren until he meets Dong-hyeon, who calls herself a vampire because she suffers from hemophilia. Unlike Dong-hyeon, when Nam-soon is injured, she bleeds from even the smallest wound. As the two grow closer, Dong-hyeon suddenly begins to lose his lifelong insensitivity to pain and the hurt of a lifetime washes over him.

Hae-jin, a chef who suddenly broke up through Kakao, left for Skopelos, Greece, the same island he promised to come with for the summer vacation. Hae-jin opened a Korean restaurant called Farewell Restaurant. For couples' last farewell before their breakups, they play music and comfort them. And then one day, Eleni, a Greek girl came… and he falls in love again.
