If life is a picture book, and we are all the characters in it, then I must be the cruel female devil who kills people and sets fire, and the stupid and bad female partner who wants to break up the talented and beautiful couple. Well, that's not bad. The vicious female supporting character dies, and the male and female protagonists resolve their misunderstanding and get together. It's a standard ending.
But what if I have to start hugging the heroine's lap again? Impossible, I have to fight with fate to get back what belongs to me.
Concept: A story about the counterattack of a second cannon fodder girl
