Suddenly Became a Princess One Day
Beautiful art, gut-wrenching story filled with tears. Although the female lead grew up somewhat, it's not to the point where the story becomes flat because the author wants to pursue romance over family tragedy and drama. She's still not in good terms with her father, and she's gone backwards in this familial relationship, instead of forward. Please keep bringing the pain and tears~
I don't want to be Empress!
The art is ok, not the best art I've seen. I like the male lead slowly falling for the female lead, but I don't like how the original heroine is turning evil. A lot of villain isekai ends up with the hero becoming the villain and vice versa, so I thought this webtoon would break the trend because it wasn't like that in the beginning, but unfortunately it seems to fail my expectations.
