The fate of Bai Heqing and Cheng Yi began with the continuation of the friendship between their elders. A girl who loves flowers and plants, with the fragrance of soil on her fingertips, her eyebrows like green grass hide her dedication to crop growth; the other is a girl who is easy to move between business competitions and clubs, her eyes like stars are full of wisdom in doing things. The friendship established by the cooperation between the elders allowed the two to grow up together. Bai Weiqing often had mints prepared for Cheng Yi in his pocket; Cheng Yi's notebook contained leaf specimens of different seasons made by Bai and Qing. The desks are separated by an aisle, but they are separated by many years of bondage. The evening breeze blew past the shouts on the basketball court, past the lights of evening self-study, and past their figures side by side - from discussing the solution to a math problem, to planning differences in future directions; from sharing the melody in the headphones, to firmly reaching out when the other person was confused.
