Starts out very strong, interesting and unique.
Unfortunately as soon as the Hogwards arc starts we end up with the curse of many fanfics which is "practically retelling of original storyline with little twist". And as it stands 19 chapters in, there has been little to no change at all. Of course, there are people that can like it, and the following chapters are full of possibility... but there isn't much to hope for since MC is sorted into Griffindor at the same age as golden trio and becomes their tag along friend.
Which makes me believe this is going to be yet another "the main storyline from perspective of different character" type of story.
A shame really.
