Sun is diagnosed with Hunter Syndrome, a rare and fatal disease. He began losing his ability to walk, talk, see, and hear at just 5 years old. His single mother, Briah, has watched him slowly regress while doing everything she can to care for him. As his condition has progressed, Briah has also seen the world grow quieter around him. People have stopped noticing Sun, and other children no longer say "hi." Briah hopes other parents teach their kids that everyone is different, and it's okay to say "hi".
