So... urmn... SORRY IF THIS SUCKS!! I don't really have a lot of e brain cells well BACKSTORY TIME:

You are a 14 yr old girl, and have been in class 3E for 1month and you are bffs with Kayano, but a tragic accident happens, your older brothers, mum and dad all end up dying in a car crash after going to buy gloves (your 3week old kitten) and when a drunk driver smashed into your car only you and Gloves survive. You take 1 week of school before going back, and not telling ANYONE about the incident. You have to work every other day after school to pay rent by yourself... but what happens when a certain someone notices your change in behaviour, going from a goodie two shoes, to always skipping classes and getting in arguments.
