I think that our boy damian is actually kinda the same person throughout all her past regressions. Like in ending maker, every main or side character has had past lives before, it's just that they don't remember it. Near the end it is explained how Jude and Cordelia are just possessing the body of the character, but they are them. So maybe our boy was always damian to begin with or it might be like author's pov, but maybe less complicated. Basically, like how ren keeps being uh created? I don't even f*cking know what to called it, but maybe it's like that but damian's character/personality keeps changing until they reach a certain ending. And Elena also said something about being near damian calms her divine powers or something of the like, and it doesn't seem to be damian's body doing that but rather his soul. Idk, think of it what you will, it just some random bs that I thought up.

Elena turning a yandere sorta, not like yandere, but like possessive and obsessive? Well, something like that.

this is our FL's 3rd regression. In her second regression she meets our MC and not the villain but there she clearly hates our MC but throughout the story we get snippets from the FL's view of her realising something is amiss with our MC and he isn't acting like the villain and isn't showing his usual obsessive behavior. She eventually realises that the entity possessing the villain's body is clearly different from the original villain and hence in her reaction in the 3rd regression.

"MC is supposed to keep his distance from the heroine but he doesn't while making s*upid excuses about not doing that when he obviously wants her around" but the reason for this is that the MC wants to avoid ruin initially so he tries to break the engagement off but when he realises things are amiss and the FL wierdly doesn't hate him he decided to go through with what he wants to do and properly establishes a relationship with our FL.

the author should let us know more about the FL's second regression which is very interesting.

to save the world from ruin. Here both our MC and FL use their knowledge (with the FL using her knowledge from her previous 2 regressions) to save the world from destruction. I am thinking we might even see our MC realising that our FL might be a regressor but that is if she confesses to him however she already knows that our MC is some special entity possessing the villain but since they respect and love each other too much they might not pry too deep

they start off not liking each other but slowly start to by the end right? Wrong. The heroine loves the MC and the MC clearly loves the heroine despite what he intends to do (supposedly but I doubt he's going to break the engagement). It makes me so angry when there is no real conflict between the MC and main heroine. The MC is supposed to keep his distance from the heroine but he doesn't while making s*upid excuses about not doing that when he obviously wants her around.

the main heroine has actually reincarnated 3 times and she is currently on her 3rd regression. She fell in love with the MC during her second time and he died so she went back once more to the day they meet. I would personally rather read about her second life as it sounds like they bonded more organically than this time around and the MC actually managed to break the engagement. It also sounds like there is a major war that happens so at least it won't be all about the romance at some later point in the story. Again, the only conflict between the two right now is MC can't admit he wants the heroine and the heroine can't reveal she has memories of another life.
