yeah lol some people got it wrong. Literally the whole point of this story (better explained in the novel) is that the big mistake of their first life was that Kloff could never accept her was in love with an alpha because of his inner bias (supposed to symbolize internalized homophobia) and so he covered it up by marrying an omega that looked just like aeroc (supposed to symbolize lavender marriage of sorts), but the 2nd timeline is a "what if" scenario like what if kloff put aside his internalized bias and pride and didn't take it out on aeroc, and the 3rd is supposed to give first time line kloff a second chance. Everything about this story centers around kloff finding his way to his true love, aeroc. Only in the timelines where he choses aeroc is there peace. Rapheal was merely his pawn

Just to clarify, it has been confirmed multiple times that Kloff never loved Raphiel in any sense. If context clues and the actual story saying it arent enough, I recall the author discussing this outright.
If he loved Raphiel at all, raping Aeroc and having 6 kids with him wouldnt be the revenge.
A part of the story is about the ABO politics that held Aeroc and Kloff from being together. Raphiel is supposed to be the main vehicle to drive that plot point.
