In the dusk of Qinghe Middle School, the transfer student Lin Nian'an used a paper airplane filled with thoughts to crash into the world of the school grassroots Lu Shenzhou. When they first met, the young man's raised eyebrows and the gentle poems on the paper airplane outlined the outline of his heartbeat in the sunset.
However, family changes, academic pressure, and misunderstandings from others caused their relationship to go through twists and turns. Misunderstandings and quarrels are like haze, covering up the sweet past many times, and the loving hearts are crumbling in the face of reality. But whenever dusk falls over the campus, the paper plane carrying memories will always remind them that their original heartbeat has never changed.
As time went by, Lin Nian'an and Lu Chenzhou overcame numerous obstacles and resolved all barriers with their firm love. When the graduation bell rang, the paper planes took off again in the dusk, carrying the sincerity that rushed in both directions, towards their future.
