Entering the seventh-grade science class, Shen Hezhou and Haonan met for the first time, and they began to spend their teenage years together day and night. Haonan is a talented science master, taciturn but with a strong sense of responsibility. He habitually takes care of everyone around him, especially accompanying and protecting Shen Hezhou, who has a fair and gentle personality. However, he only defines this relationship as brotherhood from beginning to end. Hidden deep in Haonan's heart is an unspoken secret love for Lin Feihan, a classmate who loves cherry blossoms, two-dimensional dimensions, and has a slightly eldest temperament. The two admire each other, but no one has ever taken the initiative to reveal their feelings.
During their long-term companionship, Shen Hezhou developed a deep and restrained homosexuality for Haonan. He was greedy for the sense of security and gentle care given by Haonan, and secretly hid his love deep in his heart. As a good friend, he accompanied him to class, did exercises, and solved questions, and suffered the torment caused by his secret love alone. Zhang Boming in the class was always keenly aware of his depression and gave him appropriate comfort, but this warm comfort could not offset his obsession with Haonan.
During an aerospace research lecture, Shen Hezhou impulsively held Haonan's hand in the dark auditorium. Haonan did not break away. This brief intimacy gave birth to Shen Hezhou's courage to confess. He confessed his feelings under the shade of the camphor tree, and the sudden confession broke the balance between the two. Unable to respond to the feelings that crossed the boundaries between brothers, Haonan chose to deliberately distance himself, starting a cold Cold War period.
While enduring the pain of failed confession, Shen Hezhou couldn't let go of his years of friendship and worked hard to maintain superficial peace, suppressing his love and continuing to get along as friends. Haonan still pays attention to Lin Feihan silently, and the distance between the two keeps getting closer; Shen Hezhou is caught between the unrequited love and the dilemma of friendship.
A young man cannot hide his thoughts, the cherry blossoms will eventually belong to him, and the lonely boat will have nowhere to dock. When the high school entrance examination came, the two of them were completely separated at the fork in the road to enter higher education. After years of being together, they ended up with only regrets. A one-way journey that began in the midsummer of Wutong ended in nothing, leaving only the youth's unexpressed regret and sadness.
Concept: The most annoying regret of youth: you are with me day and night, talking about everything, you are filled with love, but the other person only regards you as the best brother. The confession hidden deep in my heart, after being torn apart, only alienation and dilemma remain.
