Choi Sulli ; a girl who is always alone and left by her unnies and oppas because of their busy schedules that they got but not her. She sits all alone in the seats when watch a performance or watching a movie or maybe also, eating in the SM's practice room. But she can get all happy when she gets saved from her loneliness or but if she has watched some romance movies she can get all naughty but her umma always comes back in time and stop her from watching it. Sulli is funny, nice, sweet, adorable eye-smile along with her unnie, Tiffany, but can get emotional or angry.

Lee Taemin ; a boy who was almost just like Sulli but has feelings towards a somebody. He gets left alone in the dorm by his hyungs but when that happens, like Sulli, he watches some romance or comedy, action, horror movies but when he watches the romance movies and goes out to the SM's practice room, he'll get naughty. Without his hyungs to stop him, what can they do? Taemin is clumsy, a dance-machine, nice, funny, and also sometimes a hot-tempered guy.
