She Looks Like the Supporting Actress, but She’s the Female Lead

Qin Qiansu transmigrates into the female lead of an anime about transmigration. She marries the male lead first, then falls in love with him. They love and hate each other, put one another through physical and emotional torment, and in the end, she still dies. For some inexplicable reason, she’s also bound to a System. All she can say is, “System, you’re such a dog.” Faced with a young lord who is sometimes as gentle as jade, sometimes adorably docile, and sometimes cold and domineering, Qin Qiansu wants to say, “System, sis has fallen for him. Let me go, I want him!” Only after the male lead has flirted with her until her legs go weak does Qin Qiansu realize that this male lead isn’t the one she thought he was.
