Boy Next Door’s first full‑length album, HOME, was released on June 8 2026 and sold 1,085,715 copies in its opening week, according to Hanter Chart data. The figure marks the group’s fourth straight million‑seller, following the 2024 mini‑album 19.99 and the 2025 releases No Genre and The Action.

The title track, “Viral,” entered Melon’s weekly chart for the June 8–14 period at number 50 and climbed to number 33 on the daily chart as of June 14. The single also ranks high on Apple Music and Spotify’s global charts, underscoring its reach beyond South Korea.

Boy Next Door debuted in May 2023 under KOZ Entertainment. The six‑member lineup—Sungho, Riwoo, Myung Jaehyun, Taesan, Leehan, and Woonhak—has cultivated a “boy next door” image and a sound described as easy listening with everyday‑life themes. Their early releases included the single album Who! and the EPs Why… and How?. In 2024 they expanded into Japan with the maxi single “And,” and in 2025 they issued the digital single “If I Say, I Love You.” The group’s debut headlining tour, Knock On Vol. 1, ran in December 2024.

HOME was co‑produced with Pop Time, Kako, and Zico. The album opens with the surprise lead single “Ddok Ddok Ddok” before launching into the title track “Viral.” A press release noted that the songs are meant to reflect the members’ personal experiences. Physical sales already eclipsed one million copies—a rare milestone for a group active for less than a year.

On Melon, “Viral” entered the weekly chart at number 50 and rose to number 33 on the daily chart, showing a steady upward trend. The pre‑released track “Knock, Knock, Knock” entered the weekly chart at number 92. Its performance on global streaming platforms—Apple Music and Spotify—demonstrates its reach beyond South Korea. Analysts compare the track’s clear beginning, development, climax, and conclusion, along with its synchronized dance routine, to the structure of second‑ and third‑generation K‑pop acts.

The lyricism of “Viral” centers on the group’s desire for broader exposure and a narrative about holding onto a departed lover through song. Members Myung Jaehyun and Woonhak are credited as co‑producers, highlighting the group’s hands‑on role in the creative process. The blend of heartfelt lyrics, structured composition, and choreographed performance has sparked word‑of‑mouth buzz among international listeners.

The album’s commercial success and chart performance reinforce Boy Next Door’s growing influence in the K‑pop market. Achieving four consecutive million‑seller releases in a short span is notable for a new act and reflects positively on KOZ Entertainment’s strategy. The group is set to continue promotion with the Knock On Vol. 2 tour, their second headlining concert series.

In summary, Boy Next Door’s HOME has confirmed the group’s status as a dominant act in the K‑pop industry, with record‑breaking physical sales and a strong chart presence for its title track “Viral.” The album’s success, coupled with the upcoming tour, positions the group for continued visibility on both domestic and global platforms.
