My name is Naomi Fujikawa and I am 16 years old. I live with my dad who is a photographer and a traveler. Since he travels in many different places, he met a woman named Miwa Asahina who happened to be a traveler as well. They became a great couple and were together for a while. One day, I received a call from my Dad and he said that he proposed to her and I was to make moving preparations to a place where my future brothers live. In other words, my life was to be changed forever. 13 brothers and 1 newly gained sister living under 1 roof.... I did not believe it at first, but if it was for my dad's happiness, I couldn't refuse. So, my life begins again with newly gained brothers and a new vow to take care of myself. Will I survive this sweet heaven almost every girl has dreamed of?
