KPOP DISCOVER's gugudan note

What defines gugudan is a theatrical concept plus strong individual entry points. The girl group debuted from Jellyfish Entertainment in 2016 with Sejeong and Mina out of I.O.I and Nayoung from the Produce 101 context, so individual routes into the group were already strong on day one.

Releases run from Act.1 to Act.5, each built on theatre or story. Take the brightness of Wonderland, the hook of A Girl Like Me, the polish of The Boots and the harder sound of Not That Type in order, and the change is obvious.

Because MV, Performance and Dance Practice versions all exist, the whole picture is easy to follow on video despite the short career. The units OGUOGU and SEMINA are worth holding onto as branches that explain the main group. Wonderland, then A Girl Like Me, then The Boots moves through brightness, hookiness and polish.

Editors' take Wonderland / A Girl Like Me / The Boots — three songs covering the theatrical concept and the individual characters, from the nine-piece group at Jellyfish.

Trivia worth knowing

gugudan echoes the multiplication table learned in childhood, matching a concept that combined the charms of nine members.

Release titles such as Act.1 and Act.2 point to a presentation built around stage and story.

For anyone arriving from I.O.I or from solo and acting work, that is the strongest route back here.

Impressions left by I.O.I, by acting roles and by hosting Music Core all lead back to the group.

OGUOGU and SEMINA show the roles of the members from an angle the main team does not.

The Boots, polished in both sound and visuals, is the signature song latecomers reach first.
