Paranoid Mr. Li, Please Stop Being Cruel. Miss Qin Is Innocent.

Qin Shu was willing to pay off her adoptive father's debt. For more than three years, she mistakenly believed that she could resolve her hatred. Li Sihan told her with actions that the relationship between them was just a contract. Qin Shu believed it. Some hatred could never be let go in a lifetime. But when she gave up, Li Sihan searched for her like crazy. In the days and nights without her, his world became eclipsed. The world is so big, but I have no way to escape. The world is not big, so why can't I find you? No matter how big the world is, it is only between you and me. "Li Sihan, if I had known this, why did I do it in the first place?"
