Oops! Why Did My Sanwu Senior Sister Become a Yandere?

[Become a hundred+daily+childhood sweetheart+yandere+fall in love with a yandere+become a yandere] Xia Wanju, Sanwu's aloof senior, is cold and distant to others on a daily basis. She prefers Pei Jin, and her love quietly grows but she doesn't realize it. Unexpectedly, one day Pei Jin suddenly disappeared out of thin air. After a whole month of empty suffering, she suddenly woke up that she had been deeply in love and couldn't live without him! After searching everywhere, I was dumbfounded when we saw each other again—— The former schoolmate turned into a beautiful silver-haired lady with stunning looks! When you meet again, your love will be doubled, and all the restraints in the past will collapse. After discovering that Pei Jin, who had become a girl, had lost his original identity and was alone with nowhere to stay, Xia Wanju completely transformed into a paranoid and jealous man. The lost love skyrocketed, and Xia Wanju was the first to fall in love and developed paranoid possessiveness. Taking advantage of the other person's weakness of having no identity and no support, she powerfully kept the person around her and monopolized her. Taking advantage of the situation, he grasps the weak point and entangles him forcefully, trapping his sweetheart step by step, making it clear that he will completely take over the person as his own. From now on, you can only have me in the world~ But as they got along day and night, the originally docile Pei Jin gradually became obsessed with a sickly character. He held the senior sister firmly in his palm with his backhand, and whispered softly with a smile on his face: "Senior sister, from now on you can only love me. I am yours, and you can only belong to me completely~" Two-way doting, each other is the only one, and no one can escape this unique and obsessive love.
