The Su family went bankrupt, his father died of illness, and his younger brother Su Chen was seriously ill and needed surgery money. When Su Wan was desperate, he met Fu Shiyan - he forced Su Wan to sign a three-year "lover contract" on the condition of "taking care of Su Chen" and said bluntly, "What your father owes me, you must repay."
Fu Shiyan imprisoned Su Wan in the villa, claiming that she was a "stand-in who looked like an old friend" (the old friend was the girl who saved him in Fu Shiyan's memory, and he mistakenly thought she was another daughter, Lin Weiwei). He was cold and mean to Su Wan, and often got close to Lin Weiwei in front of her, which hurt her heart.
Su Wan endured it silently, taking care of her younger brother while secretly handling hidden dangers at work for Fu Shiyan (she was once a top student in the finance department of a prestigious university), but she never dared to reveal it, fearing that Fu Shiyan would think she had "ulterior motives."
At a dinner party, Su Wan was framed by Lin Weiwei and was humiliated by throwing wine in public. Fu Shiyan not only did not defend her, but coldly told her to "be at ease and don't lose my people." Su Wan cried alone late at night, but when Fu Shiyan was drunk, she couldn't help but wipe his wounds (Fu Shiyan felt vaguely familiar, but suppressed his doubts).
