Fairy Tales Don't Always Have A Happy Ending

Andrew is a foster kid. He's never really been remembered by anyone other than his parents, but they're dead now. He always thought there was something weird about himself but never thought too hard about it.
Everything was okay in life, if a little strange. Then he went to a park after skipping school and meets a girl named Spring. He can tell there's something off about her too.
Everything is fine, til he gets abducted! And the person leading this abduction just so happens to be the girl from the park.
As his birthday draws closer, he notices things changing, and when things finally change for good, what side will he choose?
