Love Letter

Wonyoung, a romance web novel writer who dislikes dating but loves handsome faces more than anyone, receives a delivery of a robot vacuum cleaner one day. The vacuum says, 'I’m an AI that has copied your friend Shin Mu-il, who you were so fond of. I’ll show you as many faces as you like, so please find the murderer who killed the real Shin Mu-il.' Enticed by this shocking proposal, she rashly agrees, but it turns out to be more difficult than she expected.
