So the story's about a man being thrown into a body of a beautiful girl, then being forced to become an assassin or something alike. It's a pretty good idea and I haven't seen any novel or story that had this kind of idea (maybe I missed some, I'm not sure). As what the author stated in the synopsis, it's like a secret agent of sort. Handling their daily life while in the night, the killer comes out.

I don't really have anything bad to say about this story, not much has been revealed yet, since only a few chapters is out. 

There aren't enough chapters to decide whether or not the plot will be interesting, maybe it'll just be interesting in the beginning then become boring in the later parts. One problem for this story is that the MC is getting strong fast, but it was also addressed by the author so when her ability reaches lvl 3, it's much more slower to level up.

But another thing is that the pacing is a bit fast, maybe slow things down a bit so that it won't feel like your rushing things, maybe like an interaction in the gym or maybe going to a university or something, anything to slow it down. Maybe it will slow down after killing those three men. Drama is needed after all to make a story interesting, so I guess after killing those three, there'll be an interaction with the female lead or something. 

Another thing to point out is that hopefully the love interest is gonna show up soon, it's just me hoping to see it early. Not really needed to show the love interest this early in the chapters, it's just a personal preference.

Anyways I can't rate the plot yet since it's still in the early stages, while I can rate their writing style. 

4.7/5 It's not perfect but it's close to it. Honestly maybe it's just me but I find their writing style much easier to understand than the overly detailed ones or the one with too little detail.

For the characters, it'll take more time to flesh them out, so I can't rate them yet. The MC on the other hand, there wasn't much detail about their past life, though we do get to see her personality here. So I guess it's okay. 

[Edit: So in the latest chapter, it was shown how the sister felt in the other chapters. Honestly I felt like something was missing but it's quite alright. Her P.O.V was definitely something we needed to see to understand why her reactions and mood towards the MC was like that. It really brings out some uniqueness to the character, though I still have no idea what kind of personality the sister has, which idk if it's just me since I'm quite slow in the uptake.]

Honestly I'll just update this review as more chapters come out.
