You and Jokichi Yusadei are siblings, he is older by two years. You're a girl, and he's a boy. He likes Ryoba Aishi, who is one of your best friends to you.
You were with Ryoba and Jokichi, when you felt like someone took a picture of you, you turned back and saw nobody. You were feeling a bit uncomfortable, but that has been happening for the past few weeks.
