When Lin Wan picked up the leather notebook Su Zhe left behind, she never thought that she would reveal the shocking secret of her roommate.
During the day, he is a gentle and modest intern at a design institute, but his diary is full of paranoid pursuit of "White Moonlight"; on the surface, she is a new media editor in Dream City, and the memos on her mobile phone hide entrepreneurial debts that she dare not reveal to others.
A chance encounter in the kitchen late at night, a deliberately avoided phone call, and a strange lady's silk scarf on the clothesline on the balcony gradually made the two people living under the same roof peel off their disguises. When Su Zhe discovered traces of tampering in the diary, and when he encountered Lin Wan's debt collection message, the temptation and pull that started in the shared apartment suddenly turned into a two-way redemption.
