Hearts2Hearts is standing out on album and digital music charts just six months after their debut. This rookie girl group, launched by SM Entertainment, is quickly establishing a presence in both domestic and international music markets.

Hearts2Hearts is showing a strong upward trend on digital music charts with their June-released digital single title track "STYLE." The song ranked 18th on the latest weekly Circle Chart (August 17–23), rising one spot from the previous week. With this, "STYLE" has remained in the top 20 on the weekly chart for four consecutive weeks, maintaining its popularity. Notably, the 18th place is the highest ranking among debut girl group releases this year.

Hearts2Hearts is also gaining popularity in Japan. "STYLE" reached number one on the Billboard Japan Heatseekers Songs chart, which ranks songs by emerging artists gaining attention in Japan. Hearts2Hearts has maintained a top 5 position on this chart, drawing attention in the Japanese music market as well.

Hearts2Hearts officially began activities with the release of their debut single "The Chase" in February. The group consists of eight members: Yeon, Stella, Yuha, Ian, Aina, Jueun, Carmen, and Jiwoo. They are the first large-member girl group introduced by SM in 18 years since the launch of Girls' Generation in 2007. With "The Chase," they achieved first-week sales of 400,000 copies, setting a record as the highest debut sales figure. This figure is based on data compiled by Hanteo Chart.

"STYLE" is an upbeat dance track with a fresh and lively atmosphere, featuring lyrics that express curiosity and feelings toward someone. After showcasing a dreamy and mysterious charm with "The Chase," Hearts2Hearts has imprinted a bright and lovable image with "STYLE." The lively shuffle dance and performances that highlight the strengths of a large-member group have contributed to the song's popularity.

In particular, the section where member Ian performs a dance matching the lyrics "Let's walk together, I'm curious about everything" became popular as a dance challenge, garnering over 40 million views on TikTok, Instagram Reels, and YouTube Shorts.

Hearts2Hearts collaborated with the global IP content company SAMG Entertainment's character "Catch! Teenieping" to release a separate music video for "STYLE." This music video features "HatuHaping," a character version of the Hearts2Hearts members, telling a story about finding a friend's style and amplifying the message of positive confidence. This version has recorded over 3 million views on YouTube.

Hearts2Hearts was recently selected as the new advertising model for KB Kookmin Bank. KB Kookmin Bank stated that they chose Hearts2Hearts as models considering their ability to communicate closely with the youth demographic and their potential for success in the global market.

Hearts2Hearts is preparing for a comeback with the goal of releasing their first mini-album in the fourth quarter of this year. Attention is focused on whether this upcoming album will further highlight their achievements in their debut year. Based on their current success on album and digital music charts, Hearts2Hearts is raising expectations for their future activities.
