Female. The world's most positive person. She lacks tact, hates studying, and is a bit slow, but she's a kind-hearted friend. She is Hoyong's girlfriend and likes him very much. She loves writing in her diary and wants to try every job in the world. She is lifelong best friends with Eungsim and Nyamnyam. She finds washing up to be a chore.

Female. She wears glasses, but she's actually very pretty when she takes them off. She loves handsome boys. She has poor eyesight, so she wears high-prescription glasses. She is lifelong best friends with Banzi and Nyamnyam. She finds studying tedious and hates it. She finds washing up to be a chore.

Female. A classic 'pretty girl' and a beauty. Her hair is very long, reaching down to her waist. She is gentle and soft-hearted. She always washes thoroughly and smells fragrant. She is a strawberry milk lover who only drinks strawberry milk (it's her favorite thing in the world). She is lifelong best friends with Banzi and Eungsim.

Male. An incredibly popular and handsome boy. He is Banzi's boyfriend and loves every side of her (for reasons unknown;;;). He is good at studying, diligent, and has a great personality. He walks around with his bangs covering his eyes.

Male. He wears glasses, but he's a very handsome and soft-featured boy when he takes them off. With glasses on, he looks like a mischievous tough guy, but he's actually a bit frail, takes medicine, and isn't very strong. He is a strawberry milk fanatic just like Nyamnyam, only drinking strawberry milk. A self-proclaimed tough guy who appears energetic on the outside (and he is indeed very energetic). However, he is actually very kind and surprisingly gentle once you get to know him, making him fun to hang out with.

Male. The biggest prankster in school. He's always playing mean jokes on the girls, especially targeting Eungsim, and the two of them don't get along. He finds studying a hassle and just wants to play all day. Secretly, he wants to be a popular guy.

Female. Unlike Eungsim, who is pretty without glasses, she is pretty *with* her glasses on. She loves her glasses and wears them almost every day. She is soft-hearted and kind.

Female. Though she is a girl, she has a glowing, handsome-boy-like appearance. She is on the taller side. Because of her height and the way her bangs cover her eyes, she is often mistaken for a boy. When she pins her bangs back, she is a total beauty.

Female. Extremely smart and loves studying. She wears glasses and is surprisingly cute when she takes them off.

Female. A member of an idol group, but her popularity is at rock bottom. She thinks she's incredibly popular, but she gets no screen time on TV and has no fans... Her favorite food is chocolate cornet bread. She does personal live streams, but the only viewers are Eungsim, Banzi, and Nyamnyam.
