I think a lot of people come to this one expecting pure, unfiltered revenge fantasy, and it delivers that in buckets, but there's a quieter, more unsettling thread running through it. The plot kicks off with the protagonist discovering a woman, broken and discarded, and his vow to destroy those responsible. The narrative then splits effectively between his meticulous, cold preparations for vengeance and flashbacks that slowly unpack how she ended up there, which isn't just a simple victim narrative.
What stuck with me wasn't the cathartic payoff of the revenge sequences, which are certainly visceral, but the way the story questions the very vow it's built on. The protagonist's obsession starts to corrode his own sense of justice, and the woman he's avenging begins to recover and form her own agency, which sometimes conflicts with his mission. It becomes less about 'saving' her and more about whether his rage is for her benefit or his own need to fix something. The ending doesn't offer a clean resolution, leaving you with the bitter taste of what violence, even justified, takes from everyone involved.
