PART 2 of 2br br The girls from Heroes visits the YG building (i think they have a B Boy challenge and have to practice. Yoon In Na takes them to the YG Building. No Hong Chul briefly mentions that that is where Big Bang, 2NE1 and Se7en practice. I don't know why Kahi is so excited to see Big Bang considering she was a backdancer for YGE before, maybe she misses them. But I think she only knows GD and YB.
