Song Hye Sung is really in love with music since she could remember.

Most of her family members are pro-singers or talented in singing.

But being a half, she aren't lucky enough to inherit her father's talent.

She is trying her best to learn to sing and enter a music school.

Once she is in, she met a arrogant guy who thinks she doesn't deserve to be accepted into the school.

The guy always teases how she sounds and couldn't sing.

But the only thing he didn't know is, she has more soul and her diary, almost sounds like a song.

Will she make it?
