She is the grandson of the male partner's grandfather's best friend. Because her parents died unexpectedly, she was left alone with her grandfather. The male partner's mother saw how pitiful she was when she lost her parents at a young age, so she took her to live in Kyoto and gave her the best life.
But because she had a crush on the male protagonist, her confession was rejected. Knowing that the male protagonist liked the female protagonist, she kept hurting the female protagonist. When the apocalypse came, she wanted to push the female protagonist into the zombies, but the push failed and she was killed instead.
A good hand of cards was beaten to pieces by her.
After the rebirth, she decided to stay away from the heroine. Everything about her turned out to be false, but later she found out that she was not reborn, and everything was just a reminder of the end of the world given by her ancestors.
The male protagonist doesn't love the heroine, he loves her, but the ancestors didn't want her to be abducted by the male protagonist, so they deliberately created a dream for her.
But later, she was really reborn, was killed by the real book-wearing girl, and was reborn into a pink rabbit body.
