Hearts2Hearts release their first English-language single
Hearts2Hearts have put out Next Chapter, described in The Bias List's review as the group's first English-language release. The track is also a tie-in, promoting the mobile game Arena of Valor, and arrived on 16 October 2026 according to the review's publication date.
That combination — a debut in a new language attached to a game rather than a standalone comeback — is the practical heart of the story. An English-language single widens the potential audience beyond the group's existing Korean and Japanese listeners, while a game partnership puts the song in front of players who may not follow K-pop release schedules at all. Whether the song itself rewards that extra exposure is the question the review takes up, and its answer is qualified.
The Bias List's assessment is a mixed one. The review awards Next Chapter an overall rating of 7.5 and a Grade C, with sub-scores of 7 for hooks, 8 for production, 8 for longevity and 7 for the reviewer's personal bias. It is a verdict that separates the craft of the track from the way the vocal delivery is used.
What Next Chapter actually sounds like
The review characterises Next Chapter as an upbeat synth-dance track. The instrumental draws particular praise: it is described as sprightly and textured, with enough detail to keep a listener's ear engaged. The stuttering chorus is singled out as having something to it as well.
The friction, in the review's account, comes from the vocal approach. Next Chapter is said to lean heavily on sing-talk, with the reviewer describing an almost incessant need for it across the track. Verses are said to sacrifice much of the instrumental's natural movement, which in turn draws attention to English lyrics the reviewer treats as slight.
That is a specific criticism rather than a general one. The review does not argue that the production is weak; it argues that the arrangement and the vocal performance are pulling in different directions. When the review notes that the group's earlier material could make sing-talk work in small doses, it is drawing a line between a device used for effect and a device used as a default.
One aside is worth flagging for accuracy: the reviewer writes that they wished the song had a little more of what they call Neon. It is a comparison left deliberately casual in the original text, and it reads as a comment on the wider girl-group landscape rather than a claim about this track's construction.
The tie-in pattern behind a single-heavy year
Next Chapter did not appear in isolation. The review notes that Hearts2Hearts have released only one mini album in Korea this year, filling the rest of 2026 with one-off singles and other projects. Among them are the Japanese track Iconic Heart and Moonride, a tie-in with the car manufacturer Kia. Next Chapter, with Arena of Valor, is the third strand of that pattern, and it is the first to be sung in English.
That release shape matters for how the group is being positioned. A mini album is a statement of artistic intent; a string of brand-linked singles is closer to a distribution strategy, keeping the name visible across several markets and several sets of listeners at once. It gives a group multiple entry points without requiring a full body of work each time.
The trade-off is that each single carries the expectations of whatever it is attached to. A Kia campaign and a mobile game campaign come with their own audiences and their own formats, and a song written to serve one of those contexts will be judged against the group's wider catalogue anyway. The review's reservations sit in that gap: an instrumental that could carry a stronger topline, wrapped around a delivery that keeps interrupting it.
A crowded girl-group moment
The review places Next Chapter against a busier backdrop than the group's own discography. It notes that the release lands as a former SM founder is finding success with a new girl group, A2O Lite, and wonders openly how Hearts2Hearts's existing chart success will interact with that group's, or whether the two will take cues from one another.
That framing is the reviewer's, and it is offered as an open question rather than a finding. What can be said safely is narrower: the Korean girl-group field is competitive enough that a debut in a new language and a string of brand partnerships read as strategic moves, not just artistic ones. Comparrisons between groups in that climate tend to be about positioning and momentum as much as about songs.
For listeners, the more useful version of the question is not which group wins but what each one does with the attention. A tie-in single reaches people who will never read a review; a review like this one asks whether the song survives outside its campaign. Those two audiences do not always want the same thing, and a track that works as a game soundtrack does not automatically work as a standalone listen.
Why sing-talk keeps dividing listeners
The central criticism in the review is a familiar flashpoint in modern pop: the use of rhythmic, half-spoken delivery in place of melody. The review is explicit that this device can be effective, pointing to its own example of a bridge where it lands well. The objection is to volume and placement, not to the technique existing at all.
That distinction is worth holding onto when reading fan reaction of any kind. Sing-talk is a production choice with a clear function — it locks a vocal into a beat, it lets a line carry attitude where a melody would soften it, and it works well in short bursts as a contrast to a sung chorus. Stretched across verses, it can flatten the dynamics a track needs to build.
In the review's reading, Next Chapter sits on the wrong side of that line. The choruses are given credit for their stutter and shape; the verses are where the momentum is said to leak away. Since the instrumental is praised separately, the criticism amounts to an argument about arrangement and restraint rather than about the song's genre or the group's ability.
How to read a C grade
A Grade C with a 7.5 overall is not a dismissal. The sub-scores tell the story of the review more clearly than the letter: production and longevity both score 8, while hooks and the reviewer's personal preference sit at 7. That is a profile of a track whose sound world is admired and whose melodic payoff is judged to fall short of it.
Reviews of branded singles tend to be read in one of two ways. For listeners already following the group, a middling grade is a prompt to listen and decide for themselves. For anyone arriving through Arena of Valor, it is closer to a note that the song comes with an argument attached.
Neither reading requires treating one critic's grade as a verdict on a career; The Bias List's assessment is explicitly a personal one, and the review format includes a bias score that acknowledges as much.
What the review does establish is that Hearts2Hearts are working at a pace and in a range that invites scrutiny. A first English-language release is a milestone regardless of its reception, and the fact that it arrives tied to a game rather than a full project is the detail that will shape how it is remembered within the group's catalogue.
The takeaway
Next Chapter gives Hearts2Hearts their first English-language single and pairs it with one of gaming's larger mobile titles, extending a 2026 run that has already included a Japanese track and a Kia partnership. The Bias List's review credits the synth-dance production and the stuttering chorus while arguing that sing-talk dominates the verses at the expense of the song's own momentum, landing at an overall 7.5 and a Grade C.
That is a specific, arguable position rather than a consensus, and the track is available to judge on its own terms. The wider point is that tie-in singles now carry a dual burden: serving the campaign they were written for and standing up in a discography that listeners compare release by release.
