Omegaverse「αβΩ」

The uke doesn't know he is an omega, and has been living as an alpha. One day, he met his fated pair who is an elementary kid.

Note: The beginning appears as shota but the child grew up as a fine seme. Oui

The omega has to be a butler for a complete alpha household.

The uke has been doing sex service to gain money. The seme is apparently infamous with his resting bitch face.

The boss is an omega and the newbie is an alpha. Omega is a slut and will have sex with his client meanwhile alpha has bad memories with other omega.

Now Utou (beta) who used to help Karasuma (Omega) before he paired with Takaba (Alpha) has new subordinate. Sumi (Omega) is a new subordinate under Utou and has strong heat that even a suppressant is not enough. Sumi hates beta but Utou's warmth is confusing him.

Senpai, an omega is poor and has a big family. He has been living with all his might until he met the alpha, who really admires him. However, during their first meet alpha bite and mark omega.

The uke has a unique hair colour. However he lives in an era where omega are treated without mercy. One day, he met seme who has taken interest on him.

On the first chapter, I saw him taking a drug. Though it might not an omegaverse concept, I will put list it here for awhile.
