~7 months ago: the accident happened, ML fell into a coma, MC was blamed for everything unfortunate
6 months ago: ML woke up in amnesiac state; the breakup happened
Interlude: ML got to life in a house filled with memories he didn't even recall, maybe felt the gaping hole's effect quite a lot
1 month ago: the invitation to participate in the TV program, ML decision to "rekindle" the near-extinguished flame
Currently: the program is running

am i slow or we just have to make the conclusion but when between the two of them breaking up and getting in the dating show did cha yoon lose his memories? they broke up 6 months ago, but a month before he decided to go on the show. so it was literally right before the dating show he lost his memories??
