Dong-hyeon wakes up from his sleep and looks for his wife, who was sleeping next to him, but she is nowhere to be seen. He calls his wife’s name out loud, and later he feels like his head is going to split. Suddenly, Dong-hyeon remembers a scene where his wife and his friend had an affair and hit him with a car. Eventually, he came up with everything he couldn’t remember after waking up. After a little while, he can hear his wife and his friend talking outside. Dong-hyeon clears his throat and goes outside. His friend asks him if he’s okay, and Dong-hyeon responds as if he doesn’t remember anything. He became suspicious of his friend’s words, telling him about his collapse and something he couldn’t remember for five years, so he secretly followed them.
