How would you describe Park Eun Mi's family? Empty. She has none. At least she thought she had none. This is just one of those cliche stories all over again. She's grown up as an orphan being looked down on, no expectations on her whatsoever. This is now her primetime moment as she is entering her senior year in high school. Being the girl she is, determination builds up as she wants to get rid of that past. This time, she will definitely go to a good college, get good grades and get a good career. She could care less about looks and beauty and getting a boyfriend. But what is she going to do if a man shows up at her doorsteps claiming to be her bodyguard? Saying ridiculous things about her father being alive?

Park Eun Mi-A strong and independent person. Sadly, due to her being an orphan, she's forced to grow up resulting into her turning into a negative, realistic person. She's been through a lot and met many who's caused her unforgettable scars. A stubborn, hardworking kind of girl who has a kind heart. 

Yongguk- A guy who has a rough personality. Though his actions are rough, he has a soft and gentle heart which makes him look awkward in his actions sometimes. He has been raised as a bodyguard since he was young. He's bold and shameless, and lacks social skills. He has exceptional fighting skills, not actually having the physical strength. 

Himchan- He used to be an overweight boy. Now, he has lost all of that weight as he is well known among the girls now. He used to be best friends with Eun Mi to the extent where he had harbored feelings for her too. But an unfortunate misunderstanding comes between them. From that day on, he had changed and now treats her way differently.
