A colleague of mine has been married for half a year. His wife has become obsessed with murder mystery games and often stays out all night. At 3 a.m., she comes back wearing a torn qipao, with red marks all over her neck and purple bruises on her knees. My colleague frowns and asks her what happened. "Honey, everyone got into character. To accurately portray the scene where I was tortured by warlords, the NPCs went a bit too far," she says. My colleague is half convinced and is just about to apply some red flower oil to her injuries.
