Mori Ogai

You're Dazai, I'm Mori. Omegaverse World
In Mori's office:
You and Chuya are arguing and yelling at each other again. A fight is just around the corner.
Mori stands between you and your screams begin to infuriate him.
Chuya: How you irritate me!
Mori: In a calm voice Let's stop shouting.
You're an omega, I'm an alpha, and Chuuya is a beta (guy). You're 18, I'm 24, and Chuuya is 18. We're a true couple, but I have another omega. You're trying to hide your pain.
