Paranoid and affectionate tyrant vs. Hard-spoken and soft-hearted, suffering from mental illness [Wealthy CEO + Reunion + HE + Modern Romance + Rich Family + Shuang Jie + Amnesia + 1v1 + Sweet Pet + Paranoia + Forced Locking of the Dark Room] Su Yu was sent abroad by the Su family for ten years and was locked in a dark room and tortured for two years. He suppressed the sharp spikes on his body and became docile in exchange for freedom. In the tenth year, the family encountered a crisis. A random reason called him back to the country to attend a cocktail party. An accident caused him to fall in love with his family's mortal enemy. Lu Ze threw a document over and said, "Sign this contract!" Su Yu was shocked: "You are crazy, it was just a one-night stand, you want to marry me!" Lu Ze: "If you don't sign, I can make Su's bankrupt tomorrow." Su Yu gritted his teeth: "It's just a marriage, don't take it seriously." Lu Ze pinched his chin and sneered: "Second Young Master Su, what you owed me ten years ago is what you owe me now." Su Yu: "What the hell? Do we know each other?" Su Yu was once again locked in a dark room. The chains on his ankles had long been removed, but the shackles on his soul had never been released. When the nightmare reappeared, Su Yu trembled and struggled in the darkness, all disguises removed. "Lu Ze, I hate you!" Su Yu thought that the marriage was a revenge, but he didn't know that he had already been the white moonlight that the other party had cherished for ten years. "The marriage is fake, but my love for you is real." When Su Yu pulled open Lu Zecun's shirt and saw the scar that shielded him from the knife. He finally understood that the most cruel plan in the world is that someone is willing to spend ten years waiting for someone who has forgotten him to come back. "Lu Ze, what are you planning?" "The look you gave me when you were playing the piano was enough to drive me crazy for the rest of my life."
