K-Pop's #P1Harmony sits down and spills the tea on each other in this episode of #BestiesOnBesties. The boys reveal the most difficult choreography they've ever had to learn, which member is on their phone the most, and something they've never done but want to try. Learn more about P1Harmony and comment below if you agree with their votes on who has the best style, is the most photogenic, and who's the loudest!
