Lee HaRa- She is an average woman in her 20s trying to get by in life without any fuss. As a terrible dancer and awful singer, she was never able to understand those with the passion for music.

Kim Sunggyu- A music teacher at a school in Seoul. He threw away his ambitions of becoming an idol and began teaching children how to sing in hopes of inspiring them. However, he is almost always tired and usually isn't interested in anything crazy unless it's easy. Sunggyu is almost always being teased by the others for his small eyes and lack of energy, yet he is always able to gain their respect no matter what situation.

Kim Myungsoo- A savvy business tycoon with a cold thorny image and no emotions. No matter how rich he is, he cannot abandon brotherhood and therefore continued to live with the other 6 guys despite how cramped it is. Beneath his ice cold image, he has a pure and innocent heart with a hidden goofy personality and has the utmost loyalty for his friends. Although he acts like he hates HaRa, it is obvious that he doesn't!

Lee Sungyeol- Tall. Very tall and a crazy clubber. Despite his crazy dancing he can be very serious - sometimes- but most of the time he is fun and loves each person living in the household. Sungyeol is the person closest to Myungsoo and the only one that can truly vouch for his caring side.

Nam Woohyun- A failing musician that takes life however it comes as long as he gets to sing. He's known for being too cheesy and will fall for almost any girl as long as she can do a y wave, although he does have a soft spot for HaRa. His greasy personality compliments his cheesy love songs which never fail to make people cringe.

Lee Sungjong- An absolute sweetheart and the most caring person in the household. His looks are prettier than most girls as he literally could put to shame some girl group idols! He is best friends with HaRa as he is willing to listen to her daily struggles and will always take care of her needs. He also has a huge crush on her which she also acknowledges.

Lee Howon(Hoya)- A true manly man that loves to dance. Often known to be a dance machine and quite a joker. He often spends his time to use his witty sense of humour to tease the rest of the household.

Jang Dongwoo - A radio DJ and the wildest and freest. He can make anyone laugh with just one sentence! Dongwoo loves to spend his time with friends and family and will always be there to make them smile. He's usually the one people trust and is able to give advice free of charge.
