There was a ten-year emotional entanglement between Su Haoxuan and Lin Yuexin. Five years ago, Lin Yuexin was influenced by her friends to choose to go abroad for development, and made a promise to return to China and get married in five years. They reunited five years later, but she hoped that Su Haoxuan would continue to wait, and their relationship became estranged. During this period, Su Haoxuan gradually came out of the past and formed a warm family, while Lin Yuexin lost her way in the choice of emotions and life, and finally came to a tragic ending.
