Jiang Linyu entered HL University with great expectations and met Shen Guang in club activities. A thrilling helping hand on a gravel slope made Xiaoyu's wrist remember the temperature of the opponent's palm and the uncontrollable heartbeat; an ugly clay figure became the first ray of warm sunshine shining into the frozen corner of Xiaoguang's heart. They explore the corners of the city together and share their daily life on campus. More and more people are seen side by side in the camera.
However, Xiaoguang's unintentional words revealed the scar in his heart that could not be healed - his former lover Lin Muyu who died young due to illness. When Xiaoyu plucked up the courage to confess his love, what he got was Xiaoguang's cruel alienation out of fear of betraying his memory. Xiaoyu's insomnia and the figures unconsciously sketched in the picture book all tell the story of his uncontrollable heartbeat.
Xiaoyu's clumsy but sincere "poem of confession" and Xiaoguang's struggle between old things and new memories finally intersect in the cemetery shrouded in the setting sun. Xiaoguang let down his guard and revealed the deeply buried past; Xiaoyu used all his courage: "I love you, the unique Shen Guang standing in front of me at this moment."
From the first stranger to the familiar, from the boundary of friends to the intimacy of lovers, they face academic pressure, internship worries, and graduation choices together. Xiaoyu took root in G city, and a pair of toothbrushes and a pair of slippers gradually appeared in the small single room he rented. Xiaoguang chose to stay for graduate school out of love, and the group photos on the wall replaced the old portraits. They supported them through the last restlessness of youth, and in the world of fireworks, they turned the heartbeat that started on campus into a long-lasting relationship.
Intention: One person touches another person who is immersed in sadness with his sincerity, and the two people know each other and love each other.
