The leader and a high school sophomore. He calls himself the “Ultimate Genius Handsome Leader.” At school, he’s in the dance club, and after classes, he works part-time as a DJ. He absolutely adores beetles, especially the Hercules beetle—he's obsessed! He used to dislike eggplant, but recently discovered how delicious eggplant tempura is.

The 17-year-old vice-leader and high school senior. Despite his appearance, he’s a huge eater! Because he gives very precise and sharp commentary that contrasts with his gentle look, people joke that he might be “wicked,” but that’s definitely not the case.

The youngest member at 15 and a high school freshman. He’s in the tea ceremony club at school, but he honestly prefers the eating and drinking part! Besides singing, he can produce his own videos, is great at makeup, and has the best fashion sense and knowledge in the group.

The oldest at 18 and a high school senior. Fans call him the “Romantic Kansai Boy.” He has a bright, friendly personality and acts as the group's mood maker. He can read and speak Korean and has even traveled to Korea alone on a whim. He’s also incredibly diligent, having perfect attendance throughout his entire school life (except for when he had the flu!).
