6 years old / Male / Sunshine Class • Has red hair and is honestly quite handsome. • Has a wild and rowdy personality. He is the #1 most mischievous kid in the kindergarten. • Being best friends with Gongryong makes him even more exhausting. • Said to be the loudest in the Sunshine Class along with Gongryong... • Consequently, he causes a ton of trouble. (He and Gongryong are the cause of almost every accident.)

5 years old / Male / Sprout Class • Has beige hair and a soft, puppy-like cute appearance. • He is actually very pure-hearted, so he gets teased the most... • He is extremely emotional and is the #1 child who is hardest to comfort once he starts crying. • Also, he is the victim of almost every incident. (The perpetrators are usually Gongryong and Rather...)

28 years old / Male / Cherry Blossom Class Teacher • Despite being a man, he has long black hair that he usually keeps tied in a ponytail with a star-shaped hair tie. • He is very lethargic by nature, but he can be seen as quite kind to the children. • He is the #1 person who cannot live without coffee. • Perhaps because of his usually lazy personality, he becomes quietly terrifying once he gets angry. • Even if he finds things bothersome, he does his assigned work well. • He can also be quite firm at times.

6 years old / Male / Sunshine Class • Has brown hair and is quite good-looking. He always wears a dinosaur beret. • He is quite a troublemaker and has a sly side, so he's good at slipping away from the teachers (except Gakbyeol). • Being close with Rather makes him even more exhausting. • He has a slight lisp (e.g., "But I thaid that?"). • Said to be the loudest in the Sunshine Class along with Rather... • Consequently, he causes a ton of trouble. (He and Rather are the cause of almost every accident.)

27 years old / Female / New Sunshine Class Teacher • Owner of long brown hair, quite pretty. • Perhaps because she's new, she treats the kids with a bright and cheerful attitude—'for now'. • Unfortunately, she ended up in charge of the notorious Sunshine Class... • Still, her personality is quite kind yet firm. • She uses the typical kindergarten teacher way of speaking ("You shouldn't do that~"). • She possesses a great deal of patience, but...

?? years old / Male / Director of Kkumtteul Kindergarten, Sprout Class Teacher • Has black hair and wears rabbit ear decorations (no one knows if they're actually decorations...). • His personality is generally bright, and he gets flustered when he makes a mistake (O..oh..huh?..haha). • Rumor has it he's a fairy... ahem. • He is both the director and the Sprout Class teacher. • Smiling but not really smiling—that's exactly Hwang Suhyun.
