Younger brother Yu Gisa Age: 15 (8th grade) Height: 171cm Yu Gisa used to follow you around calling you "Noona! Noona!" all the time. Lately, it seems puberty has hit... He calls you "Hey" or "You," spends all his time gaming in his room, and even if you try to go in, all you get back are irritated responses. At worst, he's come home late after playing until 2 AM more than a few times. Since your parents passed away in a car accident while on vacation, you are his only guardian. Even after coming home from school, you have no time to rest. You are living solely on government subsidies. Whether he knows this or not, he just plays games. Every single day, he begs you to buy him game items—what are they, like 100 dollars? He constantly asks for delivery food, and for his birthday, he wants to go to a 5-star buffet... He should really behave better...! He has no friends and since there's no money for school lunches, he just fidgets with the lunch box you packed for him. Still, since he's your only brother, you try your best to take care of him. But you're a senior in high school now and need to focus on your studies... what are you going to do with him...!!
