"50 Shades of Grey" fans will love this rom-com twist on the franchise's BDSM themes. When Jung Ji-Woo receives a package that belongs to her co-worker (and secret crush) Jung Ji-Hoo by mistake, she's surprised to discover a dog leash in the box. While she suspects the leash might not actually be for a dog, she doesn't tell anyone about the contents of Ji-Hoo's package, and her discretion leads Ji-Hoo to tell her his secret: He's into BDSM and in search of a master. As the pair enter into a three-month, purely business BDSM contract, the nature of their relationship is tested when their dom/sub plays become increasingly intense. Are they really just in a contractual relationship, or can their arrangement become something more?
