Love Letter

Wonyoung, a romance web novel writer who dislikes dating but loves handsome faces, receives a robot vacuum cleaner with an unexpected offer. It claims to be an AI modeled on Shin Mu-il, the friend she was so fond of, and promises to show her as many faces as she likes if she finds the murderer who killed the real Shin Mu-il. Tempted by the proposal, Wonyoung rashly accepts. But solving the murder proves more difficult than she expected.
