   Summary

   The world changed when the barrier broke. With the monsters and the child ambassador came an influx of new diseases that are barely understood. You're a young scientist and have been called upon to work with monster-kind to help treat these strange new conditions, but you begin to notice that you have changed alongside the world - more so than you could possibly imagine.

   High jinks and low jinks ensue. WARNING: contents include spicy bone-zoning, VERY slow burn, painful hanahaki experiences for the mc & more :))
