"Villain on the Second Floor"[3]) is a 2010 South Korean crime comedy film written and directed by Son Jae-gon about a depressed widow who rents out a room to a suspicious man who claims to be a novelist.

[4] Yeon-joo, a depressed widow, lives with her bad-tempered daughter, Seong-ah, who's an ex-child model but is now being bullied in school.

Now deep in debt, Yeon-joo decides to rent out a room in her house to a mysterious man named Chang-in who introduces himself as a novelist.

Unbeknownst to her, Chang-in is a thief who's trying to get his hands on a set of Ming Dynasty tea utensils that her deceased husband stole.

"[1] James Mudge of Beyond Hollywood described it as "a breath of fresh air" that "[refuses] to comply with the usual tired genre clichés.
