Lee Junghwan's dream was to be a singer, his looks has been a barrier of that for so many years. At some point he almost quits, but then he met Ji Seungyeon and his world changed.

   Seungyeon was a beautiful girl, who found it hard to speak, and is shy around people generally, but when she met Junghwan, his gummy smile constantly made her forget that fact. 

   But like any other story, a conflict will surely ensue, will Junghwan and Seungyeon overcome it and make their dreams come true?
