After talking to Ryuji's former friends, Jun had made several observations: the first was that Kaeri was very good at acting to support the rumors she was spreading, and the second was that people didn't care enough to go against her.
He was a little disappointed, but not surprised: Ryuji's friends, like all the other students in their class, didn't know the recluse personally, and didn't plan to approach her in the future, especially because of the rumors Kaeri had spread.
