Tina was given a mission by the System: protect the female lead. Later, however, she was framed, betrayed, and tragically executed, dying right in front of Sathya. She thought completing the mission meant she could finally leave this world, but hey—what on earth does "Extraction Failed" mean?! Just like that, her consciousness remained trapped inside her lifeless body. It was then that Sathya fell into deep regret. To resurrect her, Sathya guarded her unawakening body for seventy-nine whole years. By the time the world had completely changed, Sathya had strayed onto a dark path, becoming a deeply possessive yandere who eventually fell to corruption and died at the hands of humanity. Why does she love me so much? Am I even worthy of being loved like this? When time reversed, Tina and Sathya were both brought back to the very beginning, where all the entanglements first started. This time, Tina will give everything she has to protect her fallen, yandere heroine. Yet, for some reason... Why are they calling me the yandere instead?
