Comment by BL IS LIFE on Romance, But Not Romantic - Chapter 33

heres a overview - In Omegaverse fanfiction, Imprinting is a powerful, instinctual bond, usually between an Alpha and an Omega (or sometimes another Alpha/Omega), where one character forms an immediate, unbreakable attachment to their fated mate upon first sight, often involving a bite and a permanent scent/psychic link, overriding other relationships and feelings, akin to soulmates but with strong biological/werewolf-adjacent roots, creating intense devotion and a unique connection. 

idk but in some omegaverse, after they imprint on each other that person can't smell other peoples phermones
