I'm writing this as someone who hasn't read the manhwa and tbh I liked it a lot. I was afraid that they would make BDSM into something that's only funny and weird but I liked how there were characters who treated it normally and not just like it's a weird kink. I liked both leads a lot like how Jiwoo was a strong woman who won't take shit from anyone like her misogynistic boss also she was really sexy in the scenes where they did a play especially the one in the red room (I screamed lmao). Jihoo was really vulnerable and honest with his feelings which I really was touched by especially when he said that Jiwoo was the one and only sun to him (I may have cried a lil). It's refreshing to see how he also owned up to his preferences in front of the disciplinary board/bosses unlike others who usually would keep quiet and let the girl/their partner take all the blame because of their pride. It also showed the proper way of BDSM as well as the wrong way so people will be educated on the difference and the importance of consent. It also showed that not only men could be problematic but also women (Jihoo's ex) could also be toxic and manipulative which is not shown a lot in media. The only thing that I have a complaint about is that I feel that the development of their feelings into love could have been shown more which would have been shown if this was a series but alas it's a movie (unless they have a part 2?). Anyways, it's worth the watch! Just don't watch this with your parents because it is really suggestive though there was no nudity so incase they walk in you're safe on that aspect lol.
