Review Detail of Neph1s in I'm A Frickin Philosopher's Stone?!!

Even though the novel only has 3 chapters (at the time of writing this review) I've never been so immersed in a story in a long time. The MC is really well written as he begins to understand the world he was in, and the setting is something that took me off guard but I was impressed either way. I haven't found any significant grammar mistakes that ruined the experience but perhaps it was a little too fast-paced and some more explanations would've been of great help. Nothing that can't be fixed in the next chaps. The beginning is spending, really looking forward to what will emerge from this!
