So you know how in other villainess/otome isekai stories, some of the protagonists seem to be a little too worried about the grand force of Fate (tm) forcing them into the path of the "original" story? Think of all those isekai'd girls who think that because the "original" story was like X, then it must always be like X; the prince will always fall in love with the heroine, the villainess will always meet a tragic end, etc. Bakarina, Bertia, et al. Now imagine if that worry actually came true, and you were stuck in a time loop of it every single life you had. Others brought up the Soleil extra chapter where it's strongly implied that falling in love with Sylvia and being cold to Illya were strongly out of his control. That he seemed to be watching himself from the third person, almost having an out-of-body-like experience while he said and did things. Same thing with Illya; loving Soleil and being unable to fully and truly hate her sister is also implied to be a "fact" of the fate prescribed to them. And where the novel is at right now, we don't know what is exactly true, but the themes of fate and trying to challenge it are super heavy. And it's an excellent read despite it all.
I'm not saying that I don't love this story, but it's just SO PAINFUL to read
