Every freshmen and junior in Chungdam high have to work in pairs and take care of a puppy.

But what if your partner isn't really who you want?

And what if this simple project will change your life?

KIM EUNJUNG

She has a pure heart and that's what makes her different from other girls. She's one of a kind because she's real and doesn't like to pretend to be perfect. But she is not a very good student and clumsy. She has a little feelings for Baekhyun but keep on denying it since she doesn't believe in "love".
