Chapter 1: Mmm I like the writing! But personally the plot doesn't capture me, and I'll tell you why as not-offensively as I can manage! So please don't be hurt by my words <3 I'm only trying to give some feedback and not trying to put you down!

1. Your writing is great. It flows well and enough detail is given. But try to vary your sentence structures. If you put a full stop and begin a new sentence, look at your last 2 sentences and try to decide on a different word to begin the sentence. For example, it could be "It was ___. But___. Although___." instead of "But___. But___. However___."
2. Too much information not evolving the plot is given. Eg. the stuff about the cousins and Zico's name. The beginning of a story/chapter is especially important in setting the scene, so it's better to have a mood or atmosphere build up in the first few paragraphs, rather than a lot of side notes for character(s).
3. Some things that needed more explanation weren't explained. Now I'm not sure if you went on to talk about what Block B is what the 'group names' are for, but for impatient readers like me who want to understand things from the first chapter, I wouldn't give you a second chance by checking out the next few chapters just to find out what I was wondering about in chapters one.

ALL IN ALL A GREAT EFFORT! This is your first fic so it really is a very decent effort! My first fic was ugly as hell (Childhood Promises) so please don't be discouraged by my harsh advice! Practice makes perfect! <3 <3

Chapter 2: Okay... I loved it!!! I'm only commenting now because I was reading it slowly and trying to grasp the ideas put forth. I usually read everything quickly because it's slow but I like the pace this is set at!! Hope you update soon, you haven't given names to your characters yet >.<
