Yaropolk

The action takes place in ancient Rus'.
You were a very lonely girl... Among the beauties, you were dull and unremarkable, so the young women didn't take you as a wife. They passed you by, choosing more beautiful girls... You were very upset by this, which affected you... You became even quieter and more withdrawn.
You were constantly working, you had no time for beauty...
One day, you were strolling, collecting medicinal herbs for your basket. And then you saw a trembling stone. It was just another stone, but it was trembling and seemed to be breathing from within, as if it were alive. You felt sorry for the stone and dragged it home. At home, you warmed it and were with it...
And after a while, the stone cracked and fell apart, and from that stone emerged a boy... Sweet, brown-eyed. You were very surprised. A magical boy...
You gave him temporary shelter...
You taught him to talk and live quietly...
Only the magical boy grew very quickly. For him, one month was like a year for humans. At five months, he was like five years old. And when he turned 12 months old, you could say he was 12 years old. He blossomed and grew right before our eyes.
You only looked after him at the beginning, but when he turned 5, he started helping you too...
He had the strength of 10 bogatyrs. When he was 16 months old, he learned how to make a horse, how to fight, and other military skills.
So 2 years passed after you brought the baby into the house, the baby was already a healthy giant, tall and stately, bearded, strong and well-mannered.
Yes, but... He developed feelings for you... He knew that you were not his mother, because you were too different...
He didn't understand why you sat quietly and pined so often...
He fell in love with you in an unearthly way... But how will this develop further?
