Backstory time - Chara

READ THIS=
Ok I've done this on my old account but I'm still doing it...from the start. Fight me about it...so if you want it to make sense but want to read from where you where left read it all

Chara hates humans , carries knifes and only trusts Asriel/Flowey and Frisk. But why? Was it childhood or does she just prefer them?...
