Hyun-su is a tall, young man appearing in his late teens, with a slender build as his diet consists of only eating ramyeon. When he went to high school he had short hair but after his classmates began to bully him, he stopped caring about his physical appearance. His hair grew longer and looked messy and he had dark eye circles because of the lack of sleep. Despite his shabby appearance, he is noted to be handsome by a few of the Green Home residents
