Yeonjun is Soobin's best friend. He likes to call Soobin "bunny" because he thinks that Soobin looks like a bunny. Soobin has been blind since birth. No doctors have been able to help for several years. As soon as Soobin turned 18, he immediately moved out from his parents so that he would not be a burden on them. Soobin tried to do everything himself, but it was difficult for a blind man to do it. One day, Soobin cut himself with blades and if not Yeonjun, he probably would have died in bath.
