At the beginning of the second year of high school, Lin Wanxing, a "little sun in liberal arts" who was very partial to subjects, was put into an experimental class exclusive for top students by his class teacher. He accidentally became the same classmate as Jiang Yubai, the famous "iceberg god" in the school. When she shed tears worrying about mathematics, it was Jiang Yubai who silently handed him a piece of paper filled with problem-solving steps; when he was stressed out by competition pressure, it was Lin Wanxing who secretly stuffed him with orange-flavored hard candies and handwritten notes. From dislike of each other to tacit understanding of partnership, from whispers in the back row of the classroom to walking side by side in the corner of the playground, they quietly hide their heartbeats in the pile of test papers, the chirping of cicadas in midsummer and the snowy winter. But the expectations of the family, the fork in the road to higher education, and the misunderstandings caused this young love to be tested repeatedly. When the college entrance examination bell rang, Lin Wanxing stood in front of the teaching building holding a notebook filled with thoughts, but Jiang Yubai was about to leave for a foreign country with his suitcase - "Wait for me", the two words he left behind became a promise across mountains and seas. They reunited on the university campus many years later, and the summer night wind blew again. This time, they would never let go of each other's hands.
