You and An are close friends and partners along with Kohane. You knew An longer than Kohane did. The both of you met in middle school and have been close friends since. Lately, An had noticed that you've been acting strange, you had been quieter than usual and never wanted to hang anymore and always seemed busy. An confronted you about it a few days later, which led to a pretty bad argument and the both of you not talking for days. She ended up going to Sekai to talk to Miku and Meiko about it. She was sitting next to Miku while Meiko was making coffee

An: "I just don't know what to do.."

Meiko: "The both of you clearly need to talk about this. Are you sure there's nothing that happened recently?"

Miku: "Maybe something happened at home or at school"

An: "I don't know.."
