Davichi will be the voices behind the theme song for KBS 2TV's upcoming drama 'Iris 2'.

Along with the duo's vocals, a 70-piece orchestra played the instrumentals for the ballad, "Do You Not Know". Kang Min Kyung and Haeri stated, "As Baek Ji Young sunbaenim's song for the 'Iris' OST 'Don't Forget' received so much love, we feel a bit of pressure, but we also want to get a better response."

In other news, the members of Davichi are preparing to release a full-length album, the second since their debut five years ago.
