Dear Charmaine... ~Park Jisung~

Jisung, a world-known idol, is living his life in preparation for his group's world tour. After days to months of practicing, he sees a written piece of paper on his desk. Unknowingly, he reads it and realizes that it was a diary entry. Every day he sees a new piece of paper end up on his desk and continuously reads them; until he notices each entry starts getting shorter and in demand for help each day, he still reads it. He doesn't know what to do in hopes of saving her life but gives it his all to be her hero.
