For Aubrey Choi, for quite awhile, 'home' meant a new house, with a new 'family'. She would stay with them for a few weeks - a couple months, at most - before being thrusted into another residence. It was an endless cycle, but it had been repeated so many times that she had grown used to it. One day, however, the cycle is broken by her forgotten brother: Choi SeungCheol. Unlike his sister's predicament, he already had a family - twelve rambunctious kids that he was responsible for supervising, whom of which Aubrey would soon come to love and care for like her blood - especially a certain tall, messy haired boy.
