Overview

In the Grand Arcane Library, Professor Thaleia finds her academic and personal focus drawn to Rin, the reserved kobold Head Librarian. Their professional bond deepens into a cute friendship laced with unspoken attraction. Driven by a need for crucial anatomical understanding, Thaleia makes an audacious proposal for a "clinical examination". The examination is intensely charged, revealing Rin's deep arousal while Thaleia exercises conscious restraint.

Consumed by lingering desire and a scientific hunch fueled by fantasy, Thaleia uncovers a revolutionary, buried truth: the kobold tail possesses a latent, highly erogenous sensitivity, activated by "prolonged and steady stimulation". This leads to an explosive, sexual awakening for Rin, awakening her body's true potential and swiftly followed by confessions of their long-held mutual crushes.

Their shared passion and scientific discovery lead to groundbreaking research that creates a paradigm shift, resulting in kobolds becoming the most sought-after romantic and sexual partners worldwide. Their love story, born from academic curiosity and secret desire, irrevocably changes the world.
