I wish that romance was just a subplot in this. The protagonist seems to have a great story and solid beliefs, but the way the story is written makes it look like all of that only amounted to so little. Not only that but the system/author makes it so that she has to choose a male lead, three at that. If the ending is her choosing to stay in that world because the men she loves are there, it's just a bad story where the protagonist is forcefully railroaded into love that may not even last that long. The protagonist doesn't even own the identity of her body, those guys could just die before her of old age, and the protagonist's hate of the author and system is completely justified. A good ending, in my opinion, would be the protagonist going back to her world, the Saintess lady and the Swordsmaster commoner guy exploring the world together after Swordmaster lost his first love, and the lady whose body she's in getting back together with the Prince guy. I don't know what would happen with the constellations after all that, but if they've lived thousands of years or more, this story would've just been a fun event to watch over in their lives. Honestly, I'd just enjoy a power fantasy with the characters being attractive, as just a slight plus. This is just my opinion, I'll still read it for a good while longer unless there'll be too much love railroading in future chapters.
