An AU where Sam Wesson is a World History teacher with a bad case of PTSD and an attractive Drama teacher for a best friend. Sam struggles with his disorder and Dean is with him through it all, but interesting obstacles come between them, including their own feelings. ((TRIGGER WARNING: PTSD, depression, anxiety, homophobia, and mentions of self-harm))

Dean is determined to set his best friend straight and Sam is more than willing to let him, because 'I'm not gay' is easier to say than 'I love you'.
