YammerS
Fans believe that YammerS was born into a broken family and suffered bullying throughout his childhood and beyond, leading to depression. He wanted to use basketball, socializing, Dota, and childhood reconciliation but unfortunately failed. His father's death was the last straw that overwhelmed him, and even his beloved Dota couldn't keep him.
