Yeah so basically he lost his memory from trying to khs and when he got better he didn’t remember anything after so they played along and his husband try to right his wrongs
He didn't get better. This was the tragic first life.
Its a flashback of the first life. At the beginning of the story they were in their second life and only ML remember what happened and was trying to make amends. Now MC is remembering the first life and seeing how awful ML use to be and how much he suffered.
I think I lost the plot a couple of chapters ago. Since the beginning of season 3, all of its a flashback right?
