Key is a bartender at the swanky Shawol Lounge, where Jonghyun has become a sleazy singer that has lost his artistic drive

Characters

Kim Kibum

The take--from-no-one bartender who's taste exceeds his budget. He doesn't settle for less. He has a very abrasive appearance to others, but he is fiercely protective of those close to him. He has a close relationship with his coworker Taemin

Jonghyun

The greasy singer that has lost his way. He sings to pay the bills now, and he rarely writes his own music anymore. Desperately in need of some inspiration

Taemin

The baby faced waiter that can charm the pants off of anyone when he wants to. He puts on a very good act, and very few actually know him. Very close to his coworker, Kibum, whom he shares an apartment with and relies on quite a bit.
