Gu Yan was hospitalized due to a salmonella allergy, and Lu Lizhi rushed to the hospital to accompany and care for him. At night, the two squeezed onto a narrow hospital bed to sleep together. When being discharged, Gu Yan's mother called and mistakenly credited the care to his friend Huo Gang. Su Jie suggested letting Lu Lizhi go handle the discharge payment. Facing the crowded payment lobby, Lu Lizhi feared crowds and fell into anxiety, so Gu Yan patiently accompanied and encouraged her over the phone. With Gu Yan's guidance, Lu Lizhi gathered her courage to complete the payment procedure. When parting at the school gate, Lu Lizhi was full of reluctance, and Gu Yan made a promise to meet and eat together on Tuesday. The two hooked pinkies to seal the promise, and only then did Lu Lizhi peacefully board her vehicle and leave.
