A girl who misses her childhood friend. She didn't realise it IS him that she sees everyday, in school after she moved to Seoul.

Being a part of Korea's popular boy band, EXO-K, Do Kyungsoo lives a normal and happy celebrity life. Practising, performing and hanging out would be his normal routine but all of this is about to change. Meet Jung Eunmi. Eunmi is just a typical fan-girl who extremely admires and adores EXO-K, but what she doesn't know is that her family and the popular Do Kyungsoo's family are connected. Two separate lives will cross, two paths that have never met will meet, and two hearts that will become one?

One night before EXO comeback of Miracles in December, D.O dreamed about a girl..........and he tried to remember everything what he dreamed....her beautiful and chubby yet cute face captured his cold freezing heart...Will he find her in real life just like a fairytale?
