Saddled with my bully

Trevor may seem like a normal teen with a good friend on his side and all the good grades he gets, but in reality he's not. At home waits an alcoholic mom and a little brother he has to take care of. On top of that his rank on school is also pretty low. You see, Trevor gets bullied, which means he has no breaks in this never ending suffering called 'life'.
When Trevor goes on a school trip to Moscow he gets paired up with his bully in everything. For a whole week they have to do assignments and activities together. Plus, they have to share a room together. A nice finishing touch is that the only place to sleep is in a double bed. Touché, school. What will happen?
