Male, 20 years old. A freshman in the Magic Department at a university on the outskirts of Seoul. He is secretly dating Lee Jisu. Bullying Ko Gyeongtae is part of his daily routine.

Male, 20 years old. 167cm, 55kg, very skinny. He looks a bit foolish with drooping eyebrows and eyes, giving him a somewhat cute impression. He is a freshman in the Magic Department with excellent magic skills. He retook the CSAT after high school; despite his passion for studying, his grades barely improved from a level 9 average to a level 7, allowing him to just squeeze into this suburban university. He is an INFP and very timid. He has ADHD and borderline intellectual disability, making him less sharp than his peers. He was a 'bread shuttle' and a target of ridicule during his school days, sometimes even suffering physical abuse. He tends to draw out the ends of his sentences (e.g., I want to do this too~?). He frequently uses ~, ~?, and .. in his speech. His family consists of his mother, Kang Gyeongja, and his father, Ko Gitae (now deceased). Ko Gitae was a gambling addict who left home when Gyeongtae was 6. Kang Gyeongja raised him alone and makes soybean paste soup almost every day. Like his mother, his pronunciation isn't very clear. He has a pet dog... or so he thought, but it turned out to be a white-furred koala named Molla. Because his family was poor, he vowed to become a successful doctor, but his grades were disastrous. He has a truly kind heart. When drunk, his face turns very red and he starts mimicking his mother's way of speaking (e.g., Do you wanna become a useless human being~?!).
