Completed[Content Warning: Non-virgin FMC] Cheng Yin is Xu Shen's "dog"—ever since he casually saved her in high school, she has spent ten years spending money for him, kneeling, blocking alcohol, and even helping his girlfriend get an abortion. Everyone scolds her for being cheap, but to her, this is a twisted form of repayment. Until Xu Shen owes a high-interest debt and uses her to repay the Macau casino tycoon Li Yaodong.
When Li Yaodong first saw Cheng Yin, he just felt this woman was like a piece of ice: she didn't resist when he humiliated her, didn't tremble when he hugged her, and even when he taught her to say dirty sweet words, it was like she was reciting a textbook. He originally wanted to discard her after getting tired of playing, but gradually became addicted to the process of chiseling open her hard shell.
But when he truly obtained her loyalty, he realized he had already become the loser—she was willing to take a bullet and go to prison for him, yet she始终 never understood what "love" is.
