Hearts2Hearts gears up for their summer comeback with the EP ‘Lemon Tang’

Following the breakout success of "RUDE!," SM Entertainment's fast-rising girl group Hearts2Hearts is set to return with their second mini-album, ‘Lemon Tang.’

On June 2 KST, the group released their upcoming project’s promotion schedule, unveiling a series of content drops leading up to the album and the title track’s music video release, including teaser images, track list, and music video teaser.

The mini-album includes the title track “Lemon Tang” and the previously released single “RUDE!,” offering a full taste of Hearts2Hearts’ bubbly, refreshing charm. Taking its name from the zesty sourness of “lemon” and the sparkling kick of “tang,” ‘Lemon Tang’ captures the group’s bright, free-spirited energy — like a radiant summer day in full swing. 

“RUDE!” marked a major career high for Hearts2Hearts earlier this year. The single topped global charts, became the group’s first music video to surpass 100 million views, and became the first K-pop girl group song released this year to reach 100 million cumulative streams on Spotify. 

The song also sparked a viral dance challenge across Korea and internationally, driven by its playful choreography and STELA’s standout English narration moment.
