Love and Leashes is a Korean sexy romantic comedy movie. Ji-woo (Seohyun) is sort of the emotionless hard worker at her office who accidentally discovers new guy Ji-hoo's (Lee Jun-young) secret: he's into BDSM, specifically being a Sub.

Because she treats this non-judgmentally Ji-hoo is encouraged to ask her if she could be his Dom. They enter into a three-month contract and Ji-woo treats it like an experimental hobby. She studies then does it to Ji-hoo and slowly learns about the lifestyle. And somewhere along the way she starts to have more romantic feeling for Ji-hoo...

The BDSM is sexy. There's a lot of narration, as if from the BDSM web site they both read, explaining the various terms and situations and what each partner is getting out of their role. I like that this is neither a sex film nor a sex-is-bad film, nor is it a romantic comedy with BDSM flavor. It's BDSM as a positive lifestyle choice.
