It's been 15 years since everything happened and everyone is in their late 20s and early 30s and most of them have kiddos.

Some of the adults still live and teach at the school, because lots of the teachers died because of the clock.

But they all keep in touch, at least for the most part. All of their kids grew up seeing each other.
But just recently the clock began to act up again, and that is why everyone gathered at the school, totally worried about what this could mean.
