We've heard of villainesses who were wronged and managed to get revenge.
Now get ready for: a saintess and a villainess understanding and supporting each other. We love seeing women support each other uwu.
Story:
The story begins from the pov of Medeia, the villainess, so it seemed to be another villainess who wants revenge story. But after she switched bodies with Psyche, the saintess, they'll both discover the difficulties of the other and why the other did what they did. Slowly they'll start to repair their broken friendship and help each other overcome their difficulties.
Medeia and Psyche discover that the people around them aren't as they seem, and most importantly that they don't have to put up with their bs. And in order not to put up with the bs of others, they'll have to fight.
It starts with a simple story of a fight between two girls over a man, and slowly develops into a story about two girls and a boy (another boy, not the man they fought over thank god) helping each other overcoming their own demons and growing so much stronger mentally. They're both so badass.
Another thing I love is how they didn't do the "omg I was wronged" thing like other manhwas with villainesses. Both the villainess and the saintess admit to the reader what they have done. Surely, they've done those things for a reason, but that doesn't excuse their action. And they don't act as if their actions are excusable. I won't get into whether those actions are actually excusable, but it's good that the author doesn't make them hide.
Characters:
Enough depth and development. You'll also discover more and more about them throughout the story, as if with every few chapters another layer of their defence is being peeled off by the author.
Art:
Pretty good. Adds to the story.
