I, the Villain's White Moonlight, Faked My Death [Quick Transmigration]

I'm an employee of the Transmigration Bureau. My purpose is to serve as a tool character and fill in the plot of each little world.

But I accidentally became the villain's white moonlight. I appeared when that murderous, gloomy, obsessive man was at his most vulnerable, saving him and giving him warmth. So he hated the whole world, but loved only me.

Until one day, I died in front of him while completing my mission.

What do you think he'll do?
