I Helped the Imprisoned Male Lead and He Became an Obsessive Man

I found myself inhabiting the body of a lowly errand child tasked with delivering meals to the male lead, Emilien, who was imprisoned as a test subject in a secret laboratory. Knowing that his eventual success would trigger a catastrophic fire that would consume the entire facility, my only goal was to escape before disaster struck. Yet, witnessing the cruelty of his experiments stirred an unexpected sympathy within me. Avoiding the watchful eyes of the researchers, I began secretly tending to his needs. Through these quiet acts of kindness, we grew closer. He asked me to give him a name, and soon after, he pleaded with me never to abandon him. Unable to refuse his desperate gaze, I promised to stay by his side. However, I knew that only the original female protagonist could cure the agonizing side effects ravaging his body. Determined to save him, I tried to slip away unnoticed so he could find his destined partner. But my attempt at departure did not go unseen. With the laboratory already engulfed in flames behind him, Emilien confronted me, his smile warm yet his eyes terrifyingly cold. His chilling fingers brushed against my cheek as his crimson eyes threatened to swallow me whole. “A good child should keep their promises,” he whispered, demanding an answer I was too paralyzed to give. My chance to run had vanished entirely.
