Premise: A guy who wants to avenge his sisters death. Went to where his sister worked and shitstorm unfolded. Conclusion: This is, a manhwa that could end in 50 chapters as there's only one main target of revenge anyway. Instead, it got trapped in side hustles, and the main story is only opening up at chapter 63. Is the story unique? Worth reading? I'd say no, but people have different tastes and some don't even care about good or bad. This is just one of those generic revenge manhwa that could have ended much earlier but the story got dragged on because why not?
