Ak Dong Musician talked about the behind story of the song, "I Love You," which swept the charts upon its release on April 24.

A part of the Original Soundtrack on the drama 'All About My Romance,' the song was written and composed by Ak Dong Musician themselves.

Lee Chan Hyuk, the brother of the two siblings, shared that "Though it is a common-themed song, the way they talk about love has unique colors that are not so commonly found in most love songs."

His sister, Lee Soo Hyun, chimed in saying, "This kind of love song may be seen as just another one in the pile of all love songs, but we did our thing to make it different, to make it pop out."

Meanwhile, Suzy, whom Lee Chan Hyuk stated is his favorite artist, sent an autographed CD and a hand-written letter to Ak Dong Musician, much to the delight of Lee Chan Hyuk.

Whether he was happier about Suzy's letter or ranking number one on music charts, Lee Chan Hyuk did not say. But the thousands of Suzy's fans already know.
