Cho Kyuhyun, a photographer and cartoonist, and Seo Joohyun—mostly known as Seohyun—a painter and sculptor, are both artists and both past lovers. Both are professional in their artistic careers, yet they still cannot fully understand the art of love. When a baby comes up into their lives, will they learn the art of love together? Or will they never truly understand it?      

Seo Joohyun, aka Seohyun, was just an ordinary highschool girl, going on with her hard life and conflicts. She was just another face on the yearbook. Just another person you'd pass by in the hallways. She was never popular like those mean girls who think they're all cool. But her life isn't just hard; it's terrible.
