Oh boy, I understand why people hate, literary HATE this one. if you are not ready for non-conformist, difficult manhwa, this one sin't for you. We, as readers, are hardly aware how little we go outside our confort zone when reading, and often find such acts distasteful. One should delve into this with a broad mind, since otherwise the point will be completely missed.
If the charachters in this manhwa were sane people with a normal amount of self estreem, this manhwa would never have been written in this way. Butt here we have damaged people, emotionally severed people, even outright crazy people. And yes, these people are all around us. And what happened here, while a bit over the top and somehow too sadistic towards the uke, is pretty posible in real life. People get back to the people who hurt them. They live with agressors. The simply just go on. Is this smart? No. Mature? No. but realistic? Bloody hell yes. In this regard both seme and uke are frightfully realistic chars. A bit underdeveloped, for sure, but their mental and emotional states are painful to behold. Yule (the seme) is in al probability a mentally unbalanced, sick young man, maybe even a borderline psychopath. The uke is almost a samochist, stemming from his unhappy childhood. They are not the character people often expect from manhwa - strong, capable, know how to do what is bets for them. Quite the contrary, these two are as messed up as can be! Even the 2nd seme, seemingly normal guy, is a borderline nutcase.
But my fave by far is the brother! he doesn't get nearly enough screen time, but he's intriguing as heck and messed up in completely different ways. An strong Oedipal complex and a a hidden BSDM devotee, I would loved for him to get a manhwa all of his own!
But now for the weak points of the manhwa. The story and psychology never quite get to the level they have to be to make this a potent, powerful manhwa. Too much rape, too much suffering, not enough depth. The uke is a terrible woobie, too much so. Literary 10 chapters should have been completely changed to reveal more about the mental states of uke, seme, 2nd seme, brother and sister. This would have made this more palatable to a wider audience and more interesting.
But regardless, this one was more than a boring, bland generic yaoi, and had so many promising points! it does not deliver fully, but still, an inetersting excursion into something more... dark and intense. Rec! just remember tpo keep a wide and open mind and gloss over the unecessary raping scenes.
