A spirited, smart and nice teenage girl, good at sports, hates her home life due to her new stepmother and stepsister. She dreams of escaping her home where she’s treated as an outsider, and one day she helps out an old man and he extends an unusual offer to her. She’s invited to come live in a giant mansion and attend a prestigious high school, where she gets to pursue her dream of becoming a veterinarian. There are four other inhabitants in this house — three beautiful brothers and one bodyguard — who are stubborn and free to do as they please. She opens their frigid hearts and they become their own little family, and find love along the way.
