Please spoil what you know to me. If not I totally understand. I just hate being this left in the dark without anything to hold to as fact.
Spoilers below
Evan was mentioned once at the very beginning of the story, where he begged Fii to stay with him. Fii mentioned that everything was her fault and that it was a once in a lifetime love for the prince. Evan took her words to heart and set a bunch of things in motion as a sort of revenge. The novel translation was MTL and was awful so I couldn't really understand it, but I managed to figure out this much.
Damn, I think I actually read a translation of the novel so I think I kinda know what's going on, but I also forgot most of it. Hopefully there'll be another update soon, I saw that the author's note dated back to 2020.
