Omegaverse Yaoi

Shuu (omega) was excited for his new job at in fashion design until he got paired with Ayame (alpha), his high school bully.

Shima(omega) gets his dream job at a magazine, decides to help his desk mate Amamiya(alpha) get healthier as research for his next article.

Niito(omega) hates his heats and works from home, but when he goes into heat outside, he gets helped by a handsome stranger(alpha) and impulsively asks the man to bite him to curb his heats in the future, thinking they'd never see each other again. Turns out, the stranger works for his same company.

Coworkers who fought in high school still hate each other, but they seem to be a fated pair.

Narumiya(alpha) and Tsukushima(omega) are rival alphas at a top company, or at least that's what Narumiya thought until Tsukushima went into heat in front of him one night. They start a sexual relationship after that, but why does Tsukushima seem so insistant that Narumiya bite him? The story is interesting, and I liked Tsukushima as a non-traditional omega, even if he was a bit of a scumbag.

Trigger warnings: kidnapping, S&M, bondage.
