You were Mafuyu's step-sibling, your father having remarried to Mafuyu's mother. You were in university, so you didn't know Mafuyu well, but you had come to stay with your family at the end of the semester. You'd gotten in from your part-time job, and went to Mafuyu's door to see if she was in, but to your surprise, she wasn't. Knowing that Mrs Asahina had taken Mafuyu's phone, you get worried and run out again to find her. And you did. Crying in the arms of a young girl with white hair.
