Hearts2Hearts sold 592,312 copies of their second mini album “Lemon Tang” in its first week — the highest first-week total of their young career, according to Hanteo figures reported by Soompi (June 2026). The album came out on June 22, 2026, and it took the group all of two days to pass their previous record. For a team that debuted barely a year and a half ago, that trajectory is the real story here, and it’s worth unpacking for anyone wondering which of K-pop’s newer girl groups is actually built to last.
What “Lemon Tang” is
“Lemon Tang” is Hearts2Hearts’ second mini album, released June 22, 2026 at 6 p.m. KST through SM Entertainment. It carries six tracks, including the pre-released single “RUDE!” and new B-sides like “15-LOVE” and “Baby Steps,” per the album details compiled by KpopOfficial and Kfriday (June 2026).
The title track is a lively dance-pop song built on sparkling rhythms and bright summer textures. The concept, as described in the release materials, plays on the lemon itself: sour and sharp on your own, sour-and-sweet together — “Lemon Tang” as what happens when “you and I” meet. It’s an unabashed summer song, arriving right as Korea’s song-of-the-summer season kicks off, and it sits at the opposite end of the group’s range from “FOCUS,” the chic house-based single they led with last fall.
The numbers, and why the speed matters
The headline stat: 592,312 copies sold between June 22 and 28 on Hanteo, comfortably clearing the group’s previous first-week record of 425,146 set by their first mini album “FOCUS,” as Soompi reported. What jumps out to me isn’t just the total but the pace — by the end of June 23, the album had already moved 440,895 copies, meaning the old record fell in roughly 48 hours, per an earlier Soompi report. “Lemon Tang” also topped Hanteo’s daily album ranking in release week, per Hanteo News (June 24, 2026), and led the Circle Retail Album Chart’s daily ranking as well, as allkpop noted.
A quick honesty check on what these numbers measure, because I think newcomers deserve it: Hanteo counts physical albums sold, mostly to committed fans, so it reads fandom size and loyalty — not general-public popularity, which shows up on streaming charts over the following weeks. But that’s exactly why the pattern matters. Every Hearts2Hearts release has out-sold the one before it. When each comeback’s floor is higher than the last one’s ceiling, that’s a fanbase compounding, not a one-off spike.
From “The Chase” to now — a fast eighteen months
Some context if the name is new to you. Hearts2Hearts is an eight-member girl group under SM Entertainment that debuted on February 24, 2025 with the single album “The Chase,” then released their first mini album “FOCUS” in October 2025, led by a house-flavored title track, as allkpop covered at the time. Since “Lemon Tang” dropped, the group has also landed an NME digital cover, the kind of Western-media nod that usually arrives a beat after the sales do.
What I find interesting is how deliberately SM has varied the menu: a cinematic debut single, a chic house track, and now a sunny summer tune. That’s a company teaching a young group range early — and teaching listeners that Hearts2Hearts isn’t locked to one mood.
My take: rookies are the best entry point in K-pop
This news is worth your time even if you’ve never heard a Hearts2Hearts song, and my reason is personal. I got into K-pop feeling like I’d walked into a party three hours late — everyone already knew the lore, the eras, the inside jokes. A rookie group flips that. Follow a team like Hearts2Hearts now and you’re early for once: the discography is three releases deep, catching up takes an afternoon, and every milestone from here — first tour, first music show grand slam, first million-seller if it comes — happens with you watching, not in a highlight reel you scroll past years later.
And “Lemon Tang” specifically is a friendly front door: a bright three-minute summer song asks nothing of you. No lore required. If it clicks, work backwards to “FOCUS” and “The Chase” and you’ll hear the group’s sound stretch in real time.
If you want the wider view of who’s releasing what this year, why 2026 is a huge year for K-pop maps the whole landscape. Eight members is a lot of faces to learn, so how to learn K-pop group members has the low-effort method I actually use. And if you’re brand new to all of this, start with getting into K-pop in 2026 — no gatekeeping, I promise.
