The cast of Soundtrack #2 - Keum Sae-rok, Noh Sang-hyun and Sohn Jeong-hyuck – chat with AsiaOne about their new K-drama, about pianist Do Hyun-seo (Sae-rok) who is torn between her ex-boyfriend, vocalist-turned-CEO Ji Su-ho (Sang-hyun), and musician K (Jeong-hyuck). Did the cast feel any pressure to live up to the success of Soundtrack #1, which starred Han So-hee and Park Hyung-sik? If Hyun-seo was a friend, would they advise her to go back to her ex or jump into a new romance? What are the soundtracks to their lives at the moment?
