It seems B2ST is popular among girl group idols as well. On the September 1st broadcast of 'Invincible Youth 2', the members of B2ST appeared as guests, much to the delight of the�cast members.

After hearing that B2ST would be coming on the show, KARA's Jiyoung in particular couldn't hold back her excitement, clasping her hands over her mouth, while the rest of the girls made plans as to what they would do when the boys arrived.

When B2ST made their appearance, the girls couldn't help but lose control as they made a fuss.
