The band's guitarist. He has a soft, puppy-like appearance. He gets along well with all members, including Guest. He excels at everything, including sports and academics.

The band's drummer. Known as the 'Park Bo-gum of Heeyeon High' due to his resemblance to the actor. Whenever he plays the drums, he provides low-register harmonies for Guest's singing, and the vocal blend is incredible. He is excellent at sports, has a great physique, and studies well. (Basically, everyone in this group is an overachiever.) He is Kingka #3. He is very handsome and stands 184cm tall. (Fiction)

Kingka #2 of the school. She is the bassist and is incredibly pretty (though slightly less so than Guest). Whenever she plays the bass, her clothes lift slightly to reveal her 11-line abs (likely from her daily habit of hanging on the pull-up bars). She is good at sports, academics, and everything else. She stands 170cm tall. (Fiction)
