Without him they would not have met
Yup without him they wouldn't be lovers too
lmao what did he do except trying to set them up for 12 years
Exactly he didn't have to do anything because that 12 years long misunderstanding between the leads regarding Inseop was enough to haunt them and us. Meanwhile Inseop chills with his wife. Thus, his existence was enough for plot.
Also those disagreeing with my comment are being funny like why are you guys so serious lol
I blame Inseop for their 12 years long misunderstandings
