(No prototype! The story is purely fictional)
Song Yan and Cheng Shengran have changed from having a crush when they were young to reuniting after a long separation as adults, but they both have a ray of moonlight in their hearts, which is each other. It's a pity that the world hates lovers. Song Yan paid a lot for her, but he died in a flight accident, and Cheng Shengran didn't know it. Several years later, she discovered that the boy had died in a plane crash. He had risked his life for her and helped her deal with many things in private, but he did not go to her. Cheng Sheng regretted those years and hid this moonlight in his heart. Later she met Zhou Fu and had a lovely daughter, but she never saw the moonlight in her heart again.
Purpose: Not all lovers can eventually get married. Cherish the people in front of you.
