8 years, the time that Ki-Woo has been one-sidedly in love with Se-Nam. It is time to end this tiresome unrequited love. After this trip, Ki-Woo planned to cut all ties with Se-Nam and be free from this feeling. But... he is suddenly locked in a 'sex room'. Ki-Woo starts having sex with Se-Nam, saying that he will let him out of this room.

"I wish the door to this room would never open."
