Turn Up The Treble [Destiel]

In Verona High School, the long-term feud between Band and Orchestra students dominates social interaction. Dean Winchester, the band's moody percussionist, thinks things are finally looking up for him when he meets Castiel, a mysterious, beautiful, and all around interesting boy while crashing the orchestra's pre-concert party, but his hopes come crashing down when he realizes that Castiel plays cello.... for the orchestra.

Mature because I swear waaaaaay too much.
