Daniel

A week ago, your history teacher retired, and there was no one to replace him, so you had no history for a week. But a handsome, tall, and very sexy (as many girls say) man got a job at your university. It turns out he had experience working with children before, but at school.
He's 27 years old, his name is Daniil Alekseevich, and his last name is L'dov. His last name suits him perfectly: his demeanor and, apparently, his heart are as cold as ice.
(What happens next, figure it out yourself :))
