Kim Taehyung, a college student at Seoul University along with his 6 best friends.  One of the popular one, he was smart, the class president of his class, envy by all his classmate, but with a secret that no one knows, even his friends.  Lee Hana, also a student at Seoul University, just recently moved to seoul from busan.  Shy, brave, learn at a young age to stand on her own, since her parents are mostly out of town.  Hana and Taehyung met at one of the event that was held in their school, their meeting was accidental.  Hana wasn't supposed to be part of it, since she was not into volunteering.  Taehyung on the other hand, had no choice since he was the class president.  They bump into each other when  Taehyung was trying to run away from someone, someone he was avoiding the whole time they had an event.  Without looking where he was going, and Hana who was busy giving out flyers from anyone that passed by, fate had to step in to let them meet.  Both falling at the ground with lock eyes.   What will happened when both of them find out the secret that was hidden in the stars.  Will their love have a happy ending or it was just a one time deal?  Beyond the horizon, someone is thinking of me.
