Hearts2Hearts Takes Senior Role for Girls' Generation's HYORISOO

K-POP girl group Hearts2Hearts is teaming up with a Girls' Generation sub-unit for a new YouTube crossover. The rookie group will appear on the "HYORISOO Project" video, set for release on the YouTube channel "Hyo's Level Up" at 6 p.m. KST on the 29th.

The HYORISOO trio is made up of Girls' Generation members Hyoyeon, Yuri and Sooyoung. Hearts2Hearts, long known as Girls' Generation fans, met Hyoyeon last year. This time they show up as seniors to the HYORISOO unit, which is preparing for its own debut.

"We've finally escaped being the youngest at SM Entertainment," the Hearts2Hearts members joke in the clip. They walk the HYORISOO trio through their group greeting, member Ayna's signature "Ayna Wink," the alter-ego personas from their in-house content, the "RUDE!" and "Lemon Tang" challenges, and even the lines they use during video-call fan sign events.

The HYORISOO members pick up on the newer fandom culture as they talk. They try the challenges and content bits together with the rookies, and react with surprise when they hear how young the Hearts2Hearts members are.

Hearts2Hearts will release its first Japanese single, "ICONIC HEART," on the 12th of next month and make its official debut in the country. Ahead of that, three tracks from the album will be released early on global music platforms on the 10th of next month.
