This review is based on just watching the movie, not knowing the webtoon, what I see makes quite a difference in rating.

I didn't know what to expect, but I think it handled that multifaceted topic BDSM quite in a good way, as far as I can judge. Especially they've done it with respect and care of the protagonists. So in that sense it gives a strong statement to respect and accept people having different desires, especially the ones not being generally accepted by "normal" society and to have an open mind and awareness to that. So many people lacking of having that mindset still. That awareness worked very well throughout the whole movie for me and made me rate it that high. Also the FL and ML were acting perfectly well I think. I hope they'll do more in the future. Also the other cast was very good.

Of course some aspects were a bit fast paced or not covered much, like their background or the transition of their relationship. That would have needed more episodes than just a movie and I wouldn't mind seeing a sequell covering that. I read that the webtoon provided more detail. But on the other hand to drag that into a 16 episode drama would've been too long and led to the usual plot problems of lengthy dramas.

So why not see that movie as a good contribution to do more stuff on such topics in society ?
