Kim Subin is a normal university student. Or so it seemed- at night, she turns from the journalism studies to dance and does what she loves. During her practices, Subin doesn't notice the pair of curious eyes watching her, always thinkning of joining her.

Subin's best friend, Lee Jimin si working at a small local café. That café isn't that normal either- it is right in the center of Gangnam, which makes it easy for a rather tall, muscular and handsome man to come for his daily dose of caffeine. What will happen?
