If you look at her face intently, her emotions are hard to read. Her smile says she's happy, but her eyes disagree. If you look at her from a glance, she seems to be judging every little movement everyone makes. If you see her in the dance studio, you see her true emotions. Some say she's beautiful, some say she's calculating. Kang Seulgi knows what everyone thinks of her, she knows when they dislike her. But she doesn't care, she doesn't even really listen to them, because inside, all she hears is the music of her heart.

Everyone agrees, Kim Jongin is a hottie. But with every hottie, there is always a flaw. His flaw?  He doesn't have friends. It's not because he doesn't like people, actually yeah it is. In Jongin's lifetime, all the important people in his life left him at some point or another.  Seen with his earphones in and a novel in hand at all times, Jongin has habitually ignored people, and often eats lunch alone on the roof.Dancing is when he can let go of all the betrayal he's felt, all the pain.  Dancing, to him, is his only friend.

Seulgi has recently moved to Seoul, South Korea to pursue her career as a dancer. She will be attending JunHo Institute of Fine Arts, a private college with only 7,000 students attending there. One of them is Kim Jongin, and like Seulgi he wants to major in the dance career. Though taking many of the same courses, they don't pay attention to each other. Each of them have their own reasons to not pay attention to anyone. Both have their own goals to achieve. 

Neither of them thought something special of each other.

Neither even acknowledged their existence.

Until they danced.
