Woojin is the textbook definition of a tease and it's making Jihoon all wobbly in the knees.

jihoon would like to think that he has his life together, but when a part of his past that he wants to forget shows up in front of him again,  his impulsive decision sets him off on the biggest rollercoaster of his life or, alternatively in which denying his feelings seems much easier to jihoon than acccepting the fact that woojin, his fake boyfriend, might become the subject of his epiphany

jihoon stays at home with a sick woojin who's playing the sims except woojin keeps killing sim-jihoon and things are about to get messy
