After the Marriage Agreement, My Arch-Enemy Turned Out to Be Really Sweet.

UI designer Su Nian, in order to cope with the family's pressure to get married, signed an "invisible marriage agreement" with Fu Sinian, the CEO of a technology company whom she met on a blind date. She thought he was aloof and taciturn because of his personality, but he already knew that she was his "old enemy" who was tit-for-tat with him in online games. Under the same roof, he planned every step and carefully planned, waiting for her to fall into the trap called "love" step by step.
