Bai Yueyue and Xia Xu are childhood sweethearts separated by a wall. From young children to young teenagers, each other is an exclusive mark engraved on each other's youth and is indispensable. Xia Xu kept his deep feelings deep in his heart, but was too timid to express them. Bai Yueyue was disheartened and quietly embarked on a flight abroad. She left for ten years, leaving only regrets.
Ten years passed, and Xia Xu moved forward desperately in regret, transforming from a young boy into a powerful business tycoon, but he never stopped looking for Bai Yueyue, and his obsession remained unchanged. Bai Yueyue worked hard to take root in a foreign country, and her career was booming. She was even lucky enough to meet her best friend Qin Xixi, and she and her son Qin Zixuan stayed with her. However, something happened, and Bai Yueyue resolutely gave up everything abroad and took Qin Zixuan on the road back home.
After returning to China, Bai Yueyue lost her youth and changed careers to restart her life. After Qin Zixuan graduated, by chance, she unexpectedly joined Xia Xu's company.
As Xia Xu's heir, Xia Yue has a very close relationship with Qin Zixuan. Bai Yueyue and Xia Xu actually misunderstood each other and regarded each other as each other's children.
When the misunderstandings were solved layer by layer, and the past regrets and debts surfaced, Xia Xu was no longer timid, and went to Bai Yueyue again with the most cautious attitude, making up for the ten years of absence and regrets little by little.
