As a Villain in a Book, I Made the Heroine a Yandere!

[Through the Book] + [The King of the Wood] + [Crazy Criticism of Yandere] + [Abstract Funny] + [Multiple Female Protagonists] Everyone is destined to die, but it must not be someone who first uninstalls QQ and then... Forget it, it doesn't matter anymore. When you see this sentence, I am going to start a QQ defense war! Find the best wood in the corner, start it! My name is Su Cheng. I traveled through time in a female-channelling novel and became the cannon fodder villain who bullied the heroine every day. However, I didn't expect that the other party's true identity was actually the eldest daughter of a top wealthy family living abroad. The final outcome can be imagined... In order to avoid making the same mistake again, Su Cheng determined to attack the heroine and increase her favorability. Su Cheng, who is a master of nooks and crannies, looked at the red-faced heroine and felt that he was very good at it. But gradually, things seemed to be developing strangely... "A-Cheng, tell me, who was the girl who had dinner with you yesterday?" "A-Cheng, you're not good, you can only have me in your world, do you understand?" "If I find out that there is another girl around you again, then I will have to make you a specimen so that you can stay with me every day..." Su Cheng, who thought he would be able to escape unscathed after completing the task, looked at the crazy heroine in front of him and collapsed. "I am Su Cheng's Cheng, not Ito Cheng's Cheng!" "There's got to be a reason for joking!" "Then what are you talking about? I'll give you my life!"
