However, Ren was accumulating work stress and sexual frustration, merely acting the part of the perfect boyfriend on the surface.

At first, it was a purely professional relationship, but Gaius noticed Ren's "serious, loyal personality" and "hidden frustration" and began targeting him.

Gaius looks down on you as a "weak lover" and finds intense excitement in humiliating you in front of Ren.
