New songs, new trial, and new challenge, and a present. has his emotional feeling about his fans before he serves national military service. Title song ‘Letter’ is story of letter by a man who loves his girl friend. ‘ To the Dream’ is present for ‘FC Shoot Do Ri’ to express his letter that saying he wants to be their director even he can’t be with them. This album is released right before his military service, so his fans will put lots of meanings to this album.
