Transmigrated as the Villainous Male Lead in a Western Fantasy Fairytale

[Two male leads + everyone's favorite + regretful pursuit + Western fantasy] Fu Xiao was a college guy in the twenty-first century. After he rejected his yandere roommate's confession, the roommate kicked him off their dorm building. When Fu Xiao woke up, he found he'd transmigrated into a fairy-tale game he'd once trashed. In the story, Snow White was the “protagonist,” pursued by the game's many male leads. The aloof and noble Prince Pea, the scheming Snow Queen. A sweet-on-the-outside, sinister-on-the-inside second personality, and a brooding, calculating little mermaid. And he was the villainous supporting character who wandered through the whole world. Fu Xiao: “...” Honestly, he wanted no part in any of it. But the System had bound him, leaving him no choice but to follow the plot and play the “Princess Pea,” recklessly courting death. When the protagonist went on a date, he ran over and ate fifteen little cakes. When the protagonist went out on a mission, he rushed in to shield them from a monster's attack. At last, Fu Xiao got his wish, faked his death, and completed the mission. But then he saw pain and unwillingness in Snow White's eyes, though Snow White had always been gentle. Even the targets who had once despised him turned red-eyed, holding his lifeless body tightly and refusing to take a single step away in the torrential rain. Only then did Fu Xiao realize: Had he become everyone's favorite in the game? In a tower in Sicily, inside a cage woven from roses and thorns, the prince's beloved is locked away. His hair is thick and dark as raven feathers, his skin milk-white. He is a devout heretic, and also the “Aphrodite” who set the continent's war of conquest in motion. Note: 1. The ending is one-on-one, though other characters will have unrequited feelings for the protagonist. 2. No writing advice of any kind, please.
