If it were not for him, Seung-Eon feels that Ji-Wook would have already died from selling his organs. At first seeing him in what he called his seat, Seung-Eon asked who Ji-Wook was and why he was there before saying he should just move. Hearing that Ji-Wook was two years older than him, Seung-Eon retorted that he looked like a child now is talking like one too. Giving Ji-Wook some textbooks since he said he was poor, Seung-Eon also hands him something to go and buy food with. With Ji-Wook approaching, Seung-Eon told his friend Junyoung who he was was with to go. Aware that he is being watched while eating, Seung-Eon asks Ji-Wook if he has never seen a person eat before instructing him to stop staring and eat. With Ji-Wook saying he has more to pay back, Seung-Eon tells him to throw the cash away. When Junyoung tried to call him, Seung-Eon instructs him to buy the medicine for indigestion, and coffee. Seung-Eon speaks further freely how the food tasted like trash, he only ate it since Ji-Wook was there. Entering the room to see Hyungseo speaking with Ji-Wook, he asks the latter what was said for him to smile like that, even though Ji-Wook had no such expression. Seung-Eon tells Ji-Wook not to speak to him, and his anger is then directed towards Hyungseo. Outside he gently pokes Ji-Wook's cheek and tells him when someone is speaking to look at them. Seung-Eon's hobbies are listed as reading and exercise.
