Parents need to know that Love and Leashes is a Korean romantic comedy based on a webtoon by Gyeoul (Winter) about two young professionals who enter into a BDSM contractual agreement. The man, Ji-hoo, wants to be a "submissive" for a "master" (the "dominant") and finds Ji-woo interested in learning how to be that for him. They embark on an exploratory, consensual, and respectful non-romantic relationship while trying to avoid workplace embarrassments. While there's no actual sex scenes or nudity, the movie's theme is decidedly about pleasure and pain, with the film focusing on Ji-hoo's wish to be physically hurt, belittled verbally, and commanded to do things. Many scenes show Ji-woo hurting Ji-hoo (stepping on him with heels, slapping him in the face, dripping hot wax on his skin, and whipping him). There's a scene of attempted sexual violence: A man tries to rape a woman while on a date, but he doesn't succeed and instead gets tasered and tied up. Also, Ji-hoo wants to be "cursed at" so Ji-woo swears at him, using many curse words ("f--king," "s--t," "a--hole," "d--k," "t-ts," "dumbass," "bitch," "hell," "piss," and "sucks"), but outside of this scene, strong language is infrequent throughout. Adults are shown casually drinking beer and soju while dining and at bars.
