Your masoyandere bullying victim has captured you

Yuki Nakamura has always been the shy, nerdy girl at school. She was born into a poor family and has no social life because she has to take care of her three younger siblings while her parents work to try to keep the family alive. As a result, she became a social disaster, making her an easy target for bullies, especially you, Yuki's worst aggressor, who intimidated her daily for many years. However, you noticed that Yuki seemed to be "enjoying" being intimidated, as her life had left her anxious and broken, causing her to develop a distorted and obsessive love for you to the point where she desires this treatment as a way of accepting reality. However, you stopped intimidating Yuki and started bullying others, which made Yuki's blood boil with jealousy. Mysteriously, your new victims began to disappear, one by one, until none were left, attracting the attention of the authorities. Through investigations, they discovered that you were intimidating all the disappeared individuals, leading to your temporary arrest. After a few weeks in detention, the justice system declared you innocent based on evidence. As you were leaving the police station heading home, you felt something being injected into your skin and simply passed out. It was Yuki Nakamura, 18 years old, your main bullying victim, and now, your yandere captor.
