I’m looking for a vertical drama that I was watching. I lost the link.
It’s about two sisters that come across a demon and they have the choice to choose beauty or intelligence. The evil sister chooses beauty the first time, while the good sister chooses intelligence. Despite her initial success, the evil sister ultimately kills her. However, they are reborn, and the evil sister chooses to embrace intelligence. The demon tells her that she only wants be beautiful and looked at by others. But she says something like, “Brains are what run the world,” or something similar. The good sister, who retains memories of her past life chose beauty and is still incredibly intelligent. Everyone in the school loves her, and she even tutors the school bully. The evil sister, who demonstrates intelligence, is initially portrayed as good but then she started failing her classes. I was really hooked.
