Heya, your guess is really close! But! I won't spoil it for you. The theme of this story is "destiny and ill fate". I understand your viewpoint of Soleil's infidelity, and I do wholeheartedly agree with your point, but that's only if the story ran on a mainstream love triangle situation, with or without magic. Right now, we are only on chapter 1.2 of this manga, so we have barely scratched the surface of what is truly behind the scenes. The novel has about 55 chapters, and it is hell of a deep dive, that it does become confusing and borderline sadistic (the author is a true S). I do recommend you to read the novel if you would like to under stand the full story asap, which has been fully translated and is available on Wattpad (because the updates here, although regular, take a small bit of time, because translating and cleaning is hard work). But what you said was what I also had in midn when I first started this story. So you're not alone! This is a very mind boggling and soul torturing piece, very well written, and painful to read. Loved your input!
