yes it's reincarnation that's why he knew lots of stuffs. the mystery man that raped mc was ml's brother. remember during the party or something the ml brother was talking with him in the bathroom? in their first life he was raped there, and got misunderstood by ml
Spoilerr
Yeah, only ML remember their past life memory for now. As for the rape, ML's brother rape mc first(during mc's heat). At that time ml kinda ignore/mad at mc because he stole some information his father demand, so he thought ml don't like him anymore and give him(mc) to ml's brother. So he ran out from ml's house and stay at his own house. Ml find him and find grape mark on mc's body (I forgot the detail of what happen after that) I think they kinda argue or something and then ml rape him and force imprint on him. Obviously mc traumatised because of that, he got grape twice.
This comment is biased tho I really don't like Kwon Ido. I don't like him! I don't know how many time I stop reading the novel because of him!! For now I'm his number 1 hater.
But feel free to have a different opinion than mine tho. This is just me hating kwon ido.
Oh I forgot to mention, what happen here is from their past life, not their current life. You see what their current life is in manhwa now.
Is this like reincarnation stuff? I think I read it once from the comments like the way he knew mc’s heat time and his favorites as well. If he is that mystery man who raped mc, I might need to step away from this
