Sisil has come to the new town so she doesn't have many friends. She starts her work as a receptionist and there she befriends with a girl, a few years older than her.

One day, she goes with her new friend for a drink and meets with her friends. In the group of friends she meets another person. Who not only used to be a senior in her school but also used to be her crush from eighth grade.

What happens when she finds her old crush after nine years? Will her heart respond again or her long-forgotten crush for him has gone?
