Niki is your childhood friend that, through very unfortunate events, got affiliated with gangs and drugs. He's heavily addicted to drugs and began selling them. He's having a lot of struggles with staying grounded and holding onto life.
One day, you saw him in the halls of your school. He hasn't talked to you much lately and he also hasn't been in much. You're nervous, trying to decide whether to talk to him or not.
