The Source of the Unease

I got an 'Email' from Nishino-kun.

It seemed the problem had been resolved without incident.

He said he would explain what had happened in detail once we met up.

He apologized by Email for causing us confusion.

(...Something feels off.)

It wasn't just a sense of unease; this Email didn't sound like Nishino-kun.

Someone as logical as him would normally explain what happened by Email first, rather than wait to tell us in person.

...Am I overthinking it?

(Trouble inside the 'Safe Zone'... If I had to guess, could it be that student council president?)

But Nishino-kun knew she had a brainwashing Skill, and I'd heard he'd already acquired 'Charm Resistance.'...
