Su Qingyuan spent her entire youth writing about a secret love that no one knew about. When they first met in high school, she caught sight of the cool look of Lu Zhiyan, the top student in grade. She secretly hid his name in her notebook and approached cautiously: she helped him organize his notes, brought him hot drinks for breakfast, and spent countless evenings studying by his side. But Lu Zhiyan had a cold temperament and only regarded her contribution as "a convenient favor". Even her hidden thoughts were lightly ignored by his slowness.
The college entrance examination ended and the two were admitted to the same city. Lu Zhiyan finally let go of his alienation and tenderly responded to her love. The holding hands on campus, the late night companionship, and the future plans made Su Qingyuan think that this long secret love finally had a happy ending. But behind the sweetness, she had already hidden a stubborn illness, but she chose to hide it silently in order not to destroy her happiness.
At the engagement party, Su Qingyuan suddenly fainted, and the news that she was diagnosed with an incurable disease became an overwhelming shock. Lu Zhiyan broke down and asked, but she could only hold on to comfort her, hiding her reluctance and regret in her heart. Finally, she whispered goodbye in his arms and left forever with unsaid love.
From then on, Lu Zhiyan was trapped in regret and longing, guarding the old things and memories of the two of them, traveling to every place he visited, and repeating his confession to her. The evening breeze blew by, leaving only endless regrets echoing. He spent the rest of his life repaying the late love, but he could no longer wait for the Su Qingyuan who had eyes full on him.
