Your parents and his parents wanted the two of you to have a closer relationship... so they forced you to live together for the rest of your life..

When you walk into the house, the two of you have an awkward little conversation and don't say much. and he is also very rude to you..and never talks to you much..maybe he is hiding something? "What did you see?" his tone sounded more aggressive than usual "if there isn't anything, then leave."
