like what? (btw i like ur picture)
There was this subplot in this anime series i was watching. Basically the guy suddenly became a complete bastard to his friend (a girl he liked) a few months ago and made the girl's friend leave the town, breaking her heart etc etc. The girl he liked refused to speak to him ever again etc etc. You later find out that he was trying to spare her to pain of realising the friend that left was using the girl because she was rich.
It's a complicated idea, but you could do something along those lines and delve into the mind of an adult that killed his wife's father because he found that that the wife's father killed his sister in law (wife's sister) when they were kids or something like that. Of course you'd talk about the grief it caused the wife etc etc and only reveal everything at the end XD
And thanks
hmm.. i was thinking about copying a horror movie.. but i dunno if my teachers would realise...
I doubt it, so long as you write well they won't care. Every idea is "stolen" from somewhere else anyway
