I Won't Let You Be Alone

As the best student in the grade, I was bullied, only because I was deaf! Fifteen years ago, my grandpa who is mute adopted me and raised me. Years later, my grandpa and I were bullied and humiliated by a rich man. I didn't know at that time, that he was my brother! He knew my identity but is afraid that our mother would care less about him once I returned home, so he threw away my necklace, which was the token. What should I do to protect my grandpa, and where will destiny lead me?
