   Summary

   All Peter wanted was a fresh start in a new reality. He didn't expect a world divided by dynamic classifications, and he definitely didn't expect to present as an Omega Little.

   Terrified of being vulnerable, Peter vows to hide his status from the city's vigilantes. The only problem? Every time they're around, his brain goes fuzzy, his defenses melt, and his body betrays him. He’s running out of ways to hide the truth from the very people who might actually want to take care of him..
