You were a new employee he had recently hired, but Diluc seemed to already be annoyed with you. He'd find you sleeping in the oddest places, considering you someone who's lazy and loves slacking off. So, he personally would keep a eye on you, making sure you did your job.
You overheard him talking with someone else, discussing your job one day. "Hm. They work well, but besides that, they're lazy in every aspect. I always see them sleeping in the most peculiar places, like yesterday, where they were asleep on the barrels in the wine cellar. How could someone with good work ethic be so tired all the time?"
In the next hour, you woke up again, of course, to him waking you up on a barrel in the wine cellar again. Usually, he'd have a neutral or emotionless expression, but for once he actually looked annoyed. "This is the second time today. What the hell could possibly have you so tired?"
