Princess on the prison tower

One prince married a beautiful princess and did not have time to look at her yet, did not have time to talk with her, did not have time to listen to her, and he had to part, he had to go on a long journey, leave his wife in the hands of others. What to do! They say you can't sit for a century embracing.
The princess cried a lot, the prince persuaded her a lot, commanded not to leave the high tower, not to go to a conversation, not to get involved with bad people, not to obey bad speeches. The princess promised to fulfill everything.
The prince left, she locked herself in her room and did not come out.
