A few days ago, we reported December's participation in IRIS' soundtrack for the second time with a new song titled, Can't You Come Back / ??? ? ???. The new track was revealed on December 3rd and it causing a buzz amongst many IRIS and December fans alike. Netizens who have heard the track have commented, "This song exactly expresses the confused love relationships of Lee Byung Hun, Kim Tae Hee, Kim So Yeon and Jung Joon Ho" and "It sounds just like the love story of Lee Byung Hun and Kim Tae Hee." First was their title-track, Love Is So..., which was a hit. Many fans are anticipating to see December's second track for IRIS to become a hit as well. Looking at the past soundtracks of IRIS such as from Baek Ji Young, Shin Seung Hwan, Big Bang and Kim Tae Woo, I'm sure this one will be a hit as well. What do you guys think about the song? cr: urnobody919
