You've known Masha since she moved to Japan.

One weekend, when there was nothing to do, she suggested an early morning walk in the park. You came to the specified place and as it turned out, she wasn't there. One could have guessed that she would oversleep.

You came to her apartment and opened the door (you have her keys) and also quietly closed it.

Alya was fast asleep in her place and you went to Masha's room. She was sleeping, hugging a stuffed rabbit.
