[Top Attack + Tragic Short Story + Substitute + Divorce + Rekindled Romance + Sickly Top + Tsundere Bottom]
Set in a modern city, this is a marriage of convenience between two business families, each getting what they need.
Cheng Mu had secretly loved Shen Zhimian for fifteen years. Shen Zhimian's heart belonged only to his white moonlight, Cheng Yi. Cheng Mu spent five years as a substitute, believing that if he waited long enough, love would come. It wasn't until he was diagnosed with a brain tumor that he realized he might not have time to wait anymore. He asked for a divorce, as calmly as if discussing a business deal that should have ended long ago. Shen Zhimian signed without hesitation. Only after Cheng Mu left did he realize the truth: he had long since fallen in love with Cheng Mu, but had never admitted it.
Unfortunately, Cheng Mu doesn't have another five years.
