I'll Take a Fresh Tune-Up, Romance on the Side

Tune ups are by no means an irregularity for Winry or for Edward, but there is just something about a life or death case that tends to send people over the edge a little...But it's not always for the worst. (EdwardxWinry) *Note: I wasn't sure about the rating for this one, so I marked it T for a more than minor injury and other elements*
