After the Substitute Marriage, the Hidden Tycoon and I Keep Getting Exposed Every Day

My sister ran away from her wedding, so I was forced to take her place and marry Gu Yanshen, a rising star in tech. I heard he was cold and sharp-tongued, so I decided to play the sweet, silly girl until our agreement ran its course. But married life wasn't going as expected. I stayed up late working on jewelry designs, and he took my pencil away. “Mrs. Gu, kissing is more relaxing than sketching.” I secretly entered an international competition, and he sat among the judges with a faint smile. “Are you accusing my wife of plagiarism?” The night my true identity was exposed, I cowered in the corner. “D-Divorce me!” He loosened his tie and leaned over me. “Be good. First, give me today's kiss.”
