KPOP DISCOVER's CSR note
A first love concept and the growth that came out of it hold CSR together. The seven-piece girl group debuted in July 2022, and the Korean name 첫사랑 means first love, with the fact that every member was 17 at the time sitting at the core of the concept.
The bursting freshness of Pop? Pop!, the cute confession of Loveticon and the straight-ahead bright girl pop of Shining Bright give a first-time listener a fairly complete sense of the basic colours of CSR in three songs.
In 2024 Pretty mob and the Japanese release Higher moved in a slightly more grown-up direction, and in 2026 Can't Hide Anymore restarted the Korean single activity. Following through to the newest work shows the growth out of the first love concept. Pop? Pop!, Loveticon and Shining Bright make the way in.
Editors' take Pop? Pop! / Loveticon / Shining Bright — the change from a first love concept into a growing phase in three songs, from a seven-piece on A2Z.

Japan activity score
KPOP DISCOVER original metric
No. 90/ 241 groups
No. 90 of 241 groups with recorded activity in Japan (top 37%)
- 3Japanese releases
- 8Japan-related tracks
- 1Members from Japan
- 0Official Japanese accounts
The denominator is the 241 groups, out of 564 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
