After the Breakup, My Ex-Girlfriend’s Younger Sister Took the Opportunity to Replace Her

Gu Bai doesn’t want to admit it, but he used to be someone who seemed completely emotionless—like a loyal “puppy” who would endure anything.

But patience has its limits. Repeated compromises only led to his girlfriend pushing further and further, until one day, she once again tried to threaten him with a breakup.

This time, Gu Bai agreed.

At that moment, all he felt was relief and a sense of freedom—especially when he saw the stunned, helpless look on her face.

But just as one relationship ends, another quietly begins…

His ex-girlfriend’s younger sister seizes the chance to step forward, closing the distance between them and turning everything in an unexpected direction.
