Omegaverse / A/B/O

A highly popular, biologically driven trope (often featuring M/M or F/F dynamics) where society is divided into Alphas, Betas, and Omegas. It explores intense mating instincts, heat/rut cycles, knotting, and the profound, fated bond between an Alpha and their Omega, blending primal instincts with deep emotional devotion.
