Han Eunjung,a timid girl working in a huge company, SM Entertainment. As cheesy as it sounds, she fell love at first sight with a quiet member of infamous group, EXO. 

Further believing that she should just kept her feelings bottled up as far as forever can hold, the male whom she believed didn't held any feelings towards her however felt the opposite.

With the impending problems in her life, a crazy and quiet one sided love (or so she thought) and a further twist in her once peaceful life, she continued her journey as SME make up artist and discovering that the member she fell in love with has more to offer than just being "quiet and calm".
