The 6 of them have been living together under the same roof after their parents died in a plane crash. From strangers, they grew closer to each other until they become as close as real siblings. They love each other just like any other siblings. But what if he loves her not as a brother, but as a man? Foreword"where are we going, ahjussi?""why is everyone here wearing black?""when will we go home? I dont like this place.""where is mom and dad? I miss them so much."I was just 2 years old when I first put on those questions at Yang ahjussi, but I never receive any answer from him, even after 15 years.Now Im 17 and Ive been living in this luxurious house with my 5 brothers since then. Neither my brothers nor I know about what happened to our parents, we were too young back then to understand. We also dont quite remember how we end up living together in a house as siblings but what we know is that we arent blood related and we are all orphans.And this is how my brothers, Song Minho, Kim Jinwoo, Lee Seunghoon, Nam Taehyun and Kang Seungyoon, and I, Lee Jieun, live for 15 years.
