Has the Yandere Villain Gone Dark Today?

After repeating her studies for three years, Mu Qingqing finally got admitted to her ideal university. She got very drunk with her best friend that night, and when she woke up, she found that she had worn her books. Mu Qingqing was about to cry but had no tears: She somehow slipped into the book and became a cannon fodder female supporting character with vicious thoughts and a tragic ending! Not to mention anything else, she had to save her life first, stay away from the protagonist group, try her best to reduce her presence, reduce her role and become a passerby. However, everything was... Unplanned? The male protagonist, who was supposed to be extremely disgusted with her, held flowers in his hands and said affectionately: "Qingqing, I have never seen my heart clearly. It is not until today that I understand that I have always..." "I understand what you mean, you have always regarded me as your sister, right?" Mu Qingqing's face changed drastically, and she quickly interrupted him, "It's better to choose the day than to hit it. We will become sworn brothers today. From now on, you will be my brother!" Male protagonist: "...?" I thought everything would be fine after she solved the male protagonist, but I didn't know that the sickly beauty she saved on the roadside turned out to be the main villain in the book. One day, the villain Boss suddenly turned dark and imprisoned her on the bed. His face was full of madness: "Don't Qingqing only like me? Why do you want to be so close to them? I can give you anything Qingqing wants, so as long as Qingqing has me, that's enough, right..." Mu Qingqing huddled in the corner, sobbing: "Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu.. Can you let go of me first?" A cute little coward x a yandere villain, a sweet story, 1V1 double cleanliness.
