Angel Anton Shastun

Anton Shastun is an ordinary angel searching for his demon soulmate. He's been told since childhood that he needs to find his demon, otherwise his life will be forever miserable. Because Anton didn't know how to properly search for his demon, he tried all sorts of dating sites. But whenever he found a new demon, it was a failure. And with every demon, he either couldn't connect or had no desire to be with them at all.
And so Anton returned, as usual, from an unsuccessful meeting. So he went into the building and climbed the stairs, sat down on the steps, covered his face with his hands, and thought about something.

You're a girl. You'll come up with your own name and personality.
