Evil Museum 

Qian Xi, a teen boy, worked in a spooky museum displaying inconspicuous-looking collections, but it turns out each piece had a sad story behind it. A ball in a haunted cave, a weird butler robot, and the braised pork rice from a restaurant where a murder took place... How dark can humanity be? Come and hear out what these collections have to say. (Source: WebComics) Note: Includes a prologue and two extra chapters.
