The newest summer drama, "Heartstrings" has been released and already, people can't stop talking about it! Jung Yong Hwa (You're Beautiful) plays Lee Shin, lead vocalist and guitarist of popular boy band, "The Stupid". At the end of episode 2, he releases a new song titled "Because I Miss You" that is written by his character. Oddly enough, the very talented Jung Yong Hwa did in fact write the song himself outside of the drama. Anyone who follows Yong Hwa outside of kdramas knows that he's the lead vocalist/rapper/guitarist for South Korean idol group, CN BLUE. As a matter of fact, "The Stupid's" leader and drummer, Joon Hee (played by Kang Min Hyuk) is also the drummer for CN BLUE. Fortunately, Yong Hwa's efforts did not go unnoticed because shortly after the release of episode 2, "Because I Miss You" became one of the most searched topics on South Korea's main internet servers. Check out the song below and see how you like it yourself! From the music to the star-studded cast, "Heartstrings" is sure to be one of the biggest summer dramas! Watch it on DramaFever!
