KPOP DISCOVER's Hearts2Hearts note
Hearts2Hearts run on a span from quiet tension to bright pop, and on a body of work that thickens fast. SM Entertainment debuted the eight-piece girl group in 2025: The Chase set an early picture full of quiet tension, STYLE brought a bright pop feel, and Pretty Please widened it toward a soft, approachable warmth.
In 2025 FOCUS gathered six songs as the first mini album, and in 2026 RUDE! and its Japanese version added a stronger form of self-expression along with a route toward Japan.
Watching the videos means taking in Dance Practice, Performance Video and the STUDIO CHOOM family as well as the music videos. To learn eight faces and the formations they make, the shortest path is to move back and forth between the world of a music video and the footage shot closer to a fixed camera. The Chase, then STYLE, then Pretty Please covers the tension, the brightness and the warmth.
Editors' take The Chase / STYLE / Pretty Please — an eight-piece from SM whose range from quiet tension to bright pop fits into three songs.
Trivia worth knowing
The S2 inside Hearts2Hearts can be read as a heart shape, and it carries over into the fandom name as well.
As the SM girl group arriving after aespa, they invite direct comparison on visual polish and ensemble choreography.
FOCUS, the first mini album, gathers the early catalogue into one place, STYLE and Pretty Please included.
Pretty Please carries a collaboration tie to Pokémon Legends: Z-A, so the colour and character work in the music video is an entry point of its own.
RUDE! (Japanese Ver.) was an early route into the Japanese market, and the difference shows when it runs next to the Korean original.
With so many members, checking formations in Dance Practice and STUDIO CHOOM footage, not just the music videos, makes faces stick faster.

Japan activity score
KPOP DISCOVER original metric
No. 146/ 241 groups
No. 146 of 241 groups with recorded activity in Japan (top 61%)
- 2Japanese releases
- 4Japan-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.
