Are we too young for this?

Mateo is an addict. After he overdosed he was sent to rehab and now he's back and is trying to stay sober. Grayson (his best friends older brother) is back from boarding school and Mateo and him haven't seen each other since the incident that got Grayson sent to boarding school. Now that they are both back and starting school again will Mateo be able to stay sober and will Grayson be able to stay out of trouble? Will they find comfort in each other and fall for one another?
