Chen Chuyun, a quiet and well-behaved young woman, has only ever done one rebellious thing: becoming an online artist. One evening, her peaceful life is disrupted when a man named Liu Qian appears from her wardrobe, claiming to be from a distant planet and warning her of a mistake in her compatibility with Han Zi’ang. Unconvinced, Chen dismisses his claims, but Liu Qian is determined to fix the issue in his own way.
