KPOP DISCOVER's CLASSy note
CLASSy is not a group that leads with youth alone. Even inside heavy backing the core of the voice never disappears, and the strength here is that even small shifts of formation get turned into the momentum of the song.
Tear Drop carries the story of the feeling in the video, the live voice in the live clip and the line of the body in the performance clip. Watching the three in a row is the most rounded way to see where the seven stand now.
Editors' take Take hold of the origin with SHUT DOWN, then move to where the singing and the expression stand now with Tear Drop.
Trivia worth knowing
Formation
All seven members were chosen through the final rankings of an audition programme.
Name
The official spelling CLASS:y carries a colon in the middle, stacking the adjective classy on top of a fresh ':y' ending.
Fandom
CLIKE:y is the official fandom name, folding the word like into the group's own name.
Debut
SHUT DOWN comes with a zombie-themed performance clip on top of the standard music video.
Two sides
Day&Night pairs Tick Tick Boom with ZEALOUS, setting two very different moods against each other.
Latest phase
Tear Drop exists as a music video, a band-arrangement live clip and a performance film, all on the official channel.

Japan activity score
KPOP DISCOVER original metric
No. 118/ 241 groups
No. 118 of 241 groups with recorded activity in Japan (top 49%)
- 3Japanese releases
- 5Japan-related tracks
- 0Members 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.
