My Sugar Daddy Treats Me as His Younger Brother's Substitute

[Two male leads, substitute, groveling to win him back, rekindled romance, bittersweet]

Short on money, Chu Bai was forced to become Cui Che's lover.

As they spent time together, Chu Bai realized he had fallen in love with Cui Che. He confessed, Cui Che accepted, and they naturally became a couple.

Chu Bai thought he had found true love, but the appearance of one person made him realize how ridiculous he had been.

Chu Heng: the twin younger brother he had never met, and Cui Che's unattainable white moonlight.

Oh, so Cui Che never loved me. He was only using me as a substitute for his younger brother.
