It's actually very good! One of my fav manhwas
It is smut and also there is sexual violence but! Its a story about main characters' fetishes that are bdsm.
And I feel like it's good and healthy representation of this kind of dynamics. Characters care about each other, even tho there are misunderstandings between them, they still try to resolve their problems. Also they at the very beggining estabilished safe word and they both are really into their plays (im kinda sick of all of stories where one of them (usually bottom) is forcing himself or is forced to do bdsm and then magically "i now like it" without any sensible resoning). Characters here are quite hardcore and plays are violent but author made sure to emphasise the need of aftercare
I also really like the characters, they have some depth but aren't unnessecarily dark or build like some tragic figures that feel like everything will go down no matter what. Junnie and Siwon are real and possibly relatable imo
So if you like this kind of smutty hardcore bls, then i really recommend this one! You can read it whole on mangago under same tittle
