I Heard I'm the Villain's Canon Pairing

In life, Feng Ci and Yan Yunxiu had nothing to do with each other. They crossed paths only once, when Yan offered to keep him, and Feng turned him down. Then came the day Feng died. Yan rushed over in a panic, forgetting all decorum, and held him as he lay covered in blood. It seemed the whole world had forgotten Feng, except for President Yan, who was rumored to have grown ever more gloomy, cold, and ruthless. Feng hadn't thought much of it, but whenever Yan stayed up in the dead of night, pressed a hand to his chest, and hoarsely cried Feng's name, it gave him the creeps. ...Which of them was the ghost, anyway? Then Feng discovered that the world he lived in was just a transmigrate-into-a-book story. He was the white moonlight in the protagonist bottom's heart, the one who was doomed to die sooner or later. And Yan Yunxiu was an extremely unstable villainous boss, the kind even the author who transmigrated into the book instinctively kept far away from. Feng Ci: "...Hah." That character setup was so cliche. Besides, why couldn't he be the villain? Later on, the villainous boss suddenly appeared, wrapped an arm around Feng's waist, and said in a husky voice, "A Ci."
