Well, I'm glad you've enjoyed it, mate. There is a fair bit of darkness about; it's quite amusing, considering it's the first time I've written anything like it.
Good question. Absolutely nothing is solidly based on true events, if that's what you were leaning towards; not any in my life, anyway. I won't lie; some of the characters react to certain situations much like I would, but none of them are really based on anything that has personally affected me.
Mulling over it though, I think Luka, or at least his... situation, might be based on a certain individual whose path I stumbled over when I was younger... the image he projected, anyway, as I never actually met him.
Thanks, mate. o/
