Dia also wrote a hand-written letter which reads, "Although my interpretation is lacking a lot, I wanted to give a meaningful source of strength for my sunbaenim's album so I worked up the courage to sing this song. Lee So Ra sunbaenim! I am sincerely waiting for your full-length 8th album - From Dia -"

If you like more of what you hear, you can check out the original track by Lee So Ra (not to be confused with the model Lee So Ra of 'Roommate') in her 8th full-length album '8' which will be out later.�

Kiss&Cry will also hold their first solo concert 'DIA AND KISS & CRY' at Rolling Hall, Hongdae on April 18-20.
