I'm Straight! Becoming the Master of a Tragic Villain

[Stern, dignified master × cheerful, sunny disciple who’s possessive of his food on the surface + aloof beauty + coming-of-age romance + yandere contrast + clingy sweetheart] Wen Zhi, courtesy name Yaoqu, transmigrated one day and found himself in the body of a cold and aloof immortal sovereign. Wen Zhi said, “I’ve got a sword in one hand to save an old woman being hunted by demons, and another sword in the other to save a young girl being hunted by demons.” System: You’re a spy in the demonic sect! Wen Zhi: Hey, System, don’t undermine my resolve. I’m on the side of righteousness! I’m almost at max level, and you’re still calling me a spy? System: ON. ON. Please watch the footage. Wen Zhi froze. He saw a boy of thirteen or fourteen doing… Born of both human and demon blood, he was naturally endowed with a murderous streak and a possessive nature. Even being raised by the radiant and noble Shangqing Immortal Sovereign couldn’t change all of who he was. On the surface, he was a cheerful, sunny disciple. In truth, he was extremely possessive of his master and hated anyone who had an emotional connection with him. As he grew up, he spent every day imagining 108 ways to make his master his own. But he never expected… “Master, what did you put in my tea? A Sheng feels so hot…” Yan Sheng had spent more than a decade growing up in hell. His mother hated that he had been born, and his father despised him. “Master, what am I supposed to do with you? Why are you looking at other people? Why don’t you love me anymore?” One day, after more than a decade in hell, Yan Sheng was taken away by an immortal who happened to lower his head and notice him. From beginning to end, that immortal had come for him.
