fujomom's manga / #fated-pair(2)

Omega salaryman goes into heat unexpectedly and runs into a alpha on the street who “takes care” of him but is gone when he wakes up. He finds out from the TV that the alpha is a king of a foreign country.

Student Ookami, who hasn't presented as what his "gender" is (alpha, bata, or omega) is wandering the school when he comes upon an omega having sex with an alpha. When the omega, Nadame, sees Ookami he says that he's his fated pair. Ookami is stunned and has a hard time grasping what's going on and kinda gets swept up by the situation. I don't blame him by being coonfused, I was a bit too.
