My Deer Boy.

Women adore Andrey, and he loves to... use them. His life unexpectedly changes after meeting an extraordinary girl, Nastya, with whom he spends a random night. She turns out to be the granddaughter of a real witch. Nastya's granny decides to teach Andrey a lesson, who, in her opinion, offended her granddaughter and rewards the womanizer with horns. The only way for Andrey to get rid of this branchy decoration is true, mutual love.
