I read a spoiler comment before and they say that it was from another lifetime. Not sure if it's the ML that is on MC's dream but it seems like it's the ML in that lifetime.
Also, ML has the memories intact..if I'm not mistaken. So maybe he is atoning for all the misdeeds back there.
Although, I'm also not sure if what I read is really true.
It is from the first timeline and it is both the brother and Ido. The brother misunderstood the gift Ido was talking about he found Sejin in heat when he went to Ido’s house to get his gift.
In Ido’s case, the Mc provoked him and Ido thought the Sejin and Ido’s brother had an affair so out of anger and the fact Sejin wan already asking for a divorce he r@ped Sejin.
Don’t get me wrong but both Ido and Sejin were in the wrong in the first timeline and it was a very dark and tragic story of their past.
it's from both. ML's brother did r@pe him and after learning about it, ML also did the same thing so the nightmares are coming from both. also they didn't reincarnate but went back in time, so it's not their second life it's more like they had a second chance in the same lifetime.
I have a question: the constant nightmares that the MC has are about the ML or the ML brother? And if it’s the ML, is about the time he r@ped him after the ML Brother did the same or some other time?
