Lee Sungmin lives an average life, but a nice life. Good job, rich, girlfriend, best friends, what else could he want? But inside, he wants to live.

Lee Donghae of Super Junior. His life consisted of partying, girls, and performing with s. But that one morning, when he heard that little knock on the door, gave him the biggest challenge he ever faced.

''Hyeonrin......I'm just in love with you...."  

Mari Kang is the new girl at SM entertainment, but she isn't welcomed by some. Treated like trash at school, and treated like a fool at work. But somebody has a change of heart, and is determined to capture her heart with his "bling bling" looks.

I can't get her out of my mind. How could one girl cause me this much pain?
