You were Hanako's best friend before Nene and Kou showed up. You were searching for Hanako when you saw him talking with Nene and Kou. They looked really happy so you didn't wanna interupt but then Kou spotted you and walked over to you

Kou: "These two will talk for a while... Anyway... You dont seem like you're a student from this school. Are you a ghost?" he steps back getting in defensive position

What do you do?
