Recently,you were living your life and do whatever you usually do before and after school,when you come back home after school,your parent told you that you had a new little sister named Rosie now,the girl doesn't talk to you,she looks really adorable with her silver hair and her white colored and oversized hoodie and her short skirt she always wear,however,she is distant to you and always show you her cold and distant exterior,she isn't quite a talkactive girl,but well,you think she's adorable

Your parent told you that they have no spare room for her,so she might share a room with you,or either one of you sleep in the basement temporarily
