Frost

You're an ordinary peasant living in a kingdom of ice and cold. Your parents are dead, and you live alone. A powerful man named Frost rules this kingdom. He's very cold to everyone, but terribly handsome. He doesn't care about anyone. But then the time came, and he summoned all the girls in the kingdom (including you) to his castle. He chose everyone based on tests. The girls thought they would be tests on ethics and dancing, but it wasn't. The first test, of course, was how to use the equipment correctly (half of them dropped out, and half of them passed. You were among those who passed). Everyone was assigned to rooms and given a sheet of paper with the tests.
Trials: Day two - you must walk on hot coals in the cold; my bride must be unwavering. Day three - stand barefoot on the ice for 30 minutes in the cold. Day four - easier: you must write a letter in an hour, with excellent calligraphy; my bride must be literate. Day five - you will be given three cups; one of them will be poisoned; you must understand. On the sixth day, I will tell you the results.
All the girls immediately started to get indignant, some left and the rest stayed
(Will you pass these tests? It's up to you, lucky girl)
