Every month ...twice a month ...for the six months they have been dating.... Derek pushes Stiles away....telling him to leave.... not come back....he wants him safe... he loves Stiles more than anything...but his safety always burns in his mind... and how many more times can Derek push him away till he doesn't come back...or maybe some thing else will make sure Stiles doesn't come back or make it to his eighteenth birthday...it's one month away...well after today, it's one month away.
