The favored man of heaven fell suddenly and became a down-and-out gambler despised by everyone, and he blamed all of this on her betrayal. Seven years later, she returned to China with the aura of a gold medal designer, but reunited with him at a crucial bidding meeting. At that time, he was already a cold and aloof business tycoon with capital in his hands, his eyes were like daggers, and he said with tears in his eyes: "Su Wan, you owe me what you owe me, it's time to pay back." In the name of revenge, he forcefully intervened in her work and life, but in the tit-for-tat pull, he discovered that there was an unspeakable secret hidden behind the "betrayal" of the year. It turns out that her farewell without saying goodbye was achieved at the expense of youth and dreams; her journey alone was a forbearing guardianship that withstood all the wind and rain. When the dusty truth was revealed layer by layer, guilt and heartache overwhelmed the hatred. The road to reunion is filled with the gap of seven years and many obstacles from the outside world. Can they put aside their past grudges, regain their lost love through redemption and reconciliation, and let the glimmer of light penetrate the abyss to illuminate the years they spend together for the rest of their lives?
