1. Introduction to the background: Su Wan, as Shen Xiujin's contractual wife and assistant to the president, was subject to rumors of a "stand-in" in the company—colleagues commented that she had a similar appearance and habits to Mr. Shen's "White Moonlight", and Shen Xiujin's requirements for her (vetiver perfume, preference for classical music, modification of moles at the corners of her eyes) were even more confirmed.
2. Conflict in details: Shen Xiujin has a cold and harsh attitude towards Su Wan. He often corrects her habits unconsciously (such as "signing is not elegant enough"). His concentration when touching the mole at the corner of her eye makes her uncomfortable. Su Wan is filled with humiliation and confusion.
3. Memory fragments: Su Wan frequently flashed vague fragments (heavy snow, quarrels, weightlessness), accompanied by heart palpitations, and vaguely felt that the relationship with Shen Xiujin was more than just an "agreement", but the amnesia caused by the car accident made it impossible for her to verify it.
4. Key foreshadowing: Su Wan was never allowed to enter Shen Xiujin's study, making it the most mysterious forbidden area in their relationship, implying that there was a secret hidden there.
