Promised (Ciphercest)

Bill and Will have been an inseparable pair since they were born, well they're twins anyway. Anything they do or anywhere they go always together and never without the other despite the horrible environment they live in. But after a while they started to grow apart, Bill is hanging out with the bad kids and Will is the number one target of bullying in his class. When their parents died the only thing they had is each other and they started to get along like before.

Bill had promised Will that he would never leave him alone ever again... but will he keep it? or will he forget about it and abandon Will into the pit of despair.
