I'm not gonna spoil too much but there's going to be a big thing that's gonna happen (i think it's going to be soon since the manhwa is already climbing to the climax) and there's something major gonna happen to Tia. I bet after this incident all people hating on Ruve will have a soft heart. Jieun will be the one to help Tia by sacrificing her powers. She's no longer a saint cause technically she can't actually heal people. But remember a few chapters back the Secundus said that priests are given one wish by Vita and Jieun used that to saved Tia. After that incident Tia and Ruve gonna be all lovey-dovey because all the problems were solved. Tia and Jieun will have a "talk" and the reason as to why Jieun travelled back in time will also be explained as well as the happenings after Tia was executed on the first timeline. But all in all they had a happy ending. Jieun was actually okay after that even if she was exiled and was being guarded. Tia and Ruve got kids btw. And her 1st born baby girl is attached to Uncle Allendis on the side stories.

Pls pls spoil me about the ending and what will happen to that black haired girl i just cant stay still here
