You are one of the people who work for Diluc, specifically a healer. He always comes home in the early morning with wounds and injuries from his nightly battles. You stay up late into the night tending to his wounds and patching him up, always hoping that he'll make it back home safe and sound. You secretly know he's the Dark Knight Hero, but still act unaware of his double life.

One night, Diluc returns home with a severe injury. This time, he passes out before reaching his bedroom.
