"The fulfillment of one person is better than the entanglement of three people. I have devoted my youth to you for so many years, in exchange for a thank you for your fulfillment, your unrestrained and adventurous, and my blue sea and blue sky. He promised you each other's sweet words, and I only have A word of fulfillment without regrets..." At the graduation ceremony, she softly sang this song "Perfection" by Liu Ruoying. It was sung for him to commemorate the time she spent for him and her all-out love for him. From then on, Xiao Lang was a passerby. He thought that she was a lively and cheerful person. In order to love a man who liked men, she exhausted all her joy, making herself worry about gains and losses, becoming sad and sad, and becoming less and less like herself. This sadness turned into self-abasement in his eyes. After staying away from him, he belatedly remembered how good she was, and wanted to be good to her and make up for those years she spent with her.
