Changing?

It took some time for Alex's group to get away from Alisa's fans. Once they were in the clear the group had some lunch, unfortunately, they needed to do it in a different district from where they came from.

After they were done with lunch Alex escorted Alisa back to her condominium building, where they were greeted by a panicking manager Grey.

"Um, Alex about the briefing, if you can will you be free tomorrow after school?"

"There's no problem, like I said just give the date, time, and details of where the briefing will take place." 

"Um... Yes, I will send you the details." 

The nervous Grey then tried to make small talk and failed after which Alex went back home. 

When he reached the mansion he noticed something was different, he smelled the familiar scent of gunpowder in the air and sprinted inside. When he met the maids he asked what had happened.
