Yandere's Destructive Love

When he regained consciousness, he was holding the girl's chin and forcing her to drink the poisoned wine. "Drink it and you will become a puppet who only listens to my orders."... This is supposed to be the plot. But when he looked at the girl's tearful eyes, he twisted his wrist and poured the poisoned wine on the ground. "Forget it," he locked her in his arms and entangled his fingertips with her hair, "I want you to stay awake... Watch me burn down this continent for you." As a villain destined to be killed by the protagonist, he suddenly felt that turning the world into a golden cage imprisoning her seemed much more interesting than following the plot. When the imperial cavalry broke through the high wall of the academy, she grabbed the lapel of his clothes and asked tremblingly: "What exactly do you want?" He chuckled and kissed the magic mark flickering between her collarbones: "I want you to be mine for the rest of my life."
