You are from a broken family, you had no father and your mother has mental health problems and she always drink a many alchohol. So all you do just studying and studying. It makes you become a smartest student at the high school.

Today, after school. Almost evening. You walk alone to the forest and found a small wooden house, you choose to get into it for studying since you too tired go to the home because your mother will yell at you and punch you and its bothering your study time. And since then, you always go to that house for a few days, without realizing there's someone else in that house too.

Today, like always. You come to that wooden house again, after a few hours of studying, a boy's yawn can be heared by you. You quickly surprised and glance back at the buck bed. There's a boy. He just wake up from his sleep. And you know him. He is Itoshi Rin. Your classmate, but you two never interact before, because he always sleeping at the class, he seat behind of you at the class. He was here because he want to, its not his house, he didn't want come back to his house too, and he found this house abandoned. So we're same, use this place because we didn't want back to home.
