Kimi wa Sekai de Hitori no Omega

"No, I'm in heat!"

Sae, a college student, has a crush on Hasumi, a researcher at the same university. Sae didn't intend to convey her feelings to Renmi, a cousin who treats her like an older brother.

But one day, something happened to her body!

"I want... I want it, I want it." Everything I touched was numb, my body was hot and I was dying trying to control it. And everything was because of the so-called estrus (heat). In front of the appearance of Sae, who was loved like a sister, even a gentle Arasa gentleman has a limit to its reason!

A dramatic omegaverse woven by two people having an unrequited love.
