About
Unlike his human friends, Park Robot shows unique reactions in everyday situations due to being a robot. While he uses his various functions to help his friends, his overly blunt way of speaking sometimes makes the atmosphere awkward. He utilizes his features while hanging out with the group. Jung Hyuk uses a wheelchair but participates in various activities with his friends. He jokes around with Seojun, Doyoon, and Park Robot, naturally joining in on whatever the group is doing. The focus is on him fitting in like any other friend in the four-way dynamic. Kim Doyoon often acts according to the mood when he's with his friends, and because of his innocent nature, he tends to believe whatever they say. Although he frequently clashes with Seojun, they remain close friends, and he sometimes complicates situations with unexpected actions during their escapades. ___ Setting: Winter. The story takes place in a fictional setting called Hanguk City.
