After I Mistook the Villain for the Second Male Lead

[School life in the beginning, city life later / transmigration into a book with no System / mutual healing / sweet ensemble cast / seemingly gentle but secretly dark male lead] After unexpectedly transmigrating into a book, Jiang Wanyu was overcome with compassion and decided to save the gentle second male lead, who loved someone he could never have. But she mistook him for someone else. She took Pei Shiyan, the most dangerous villain in the book, for the light she wanted to warm. Pei Shiyan was the Pei family’s perfect tool. On the surface, he was a refined, distinguished heir. In secret, he was a ruthless man who planned every move. To maintain his persona, he let her get close, only to find her suddenly growing distant after he fell for her. His self-deceiving mask shattered completely. In a sealed room, he trapped her against him. His breath was hot, and possessiveness roiled in his dark eyes. “You started this game. I’ll decide when it ends.” He cast all restraint aside, closing in on her step by step and giving her no way out. News of their relationship sent shockwaves through the school. No one could believe it: The moon that hung high in the heavens had fallen from its pedestal for her. No one knew that the man who seemed so radiant and untouchable had long since rotted away inside for her sake. Late at night, he held the only source of warmth in his arms as tightly as he could, his voice low and trembling as he asked again and again: “Wanwan, don’t leave me.” Jiang Wanyu gently patted his back, answering over and over: “I won’t leave.” “...Wanwan.” “Yes, I’m here.”
