As the youngest graduate student under Lu Shiyan's sect, Su Wan had always felt that this senior professor was like a "flower on the high mountain" - knowledgeable and cool in temperament, but he treated her very differently. He would bring hot milk to her when she stayed up late to give a report, would patiently comfort her when she made mistakes in her experiments, would not be able to hide the smile in her eyes when she made progress, and would even remember all her little-known habits. From a guide on the academic road to a guardian in life, Lu Shiyan penetrated into Su Wan's life little by little with his gentleness. There are no bloody misunderstandings, only the sweetness of two-way running. This nurturing love that started on campus is when he spoils her like a princess and she spends the rest of his life with him. It is a sweet two-way redemption and preference.
