Ryan's status here is a bit odd—not exactly a prisoner, but he definitely can't leave just yet.
It seems Alice has instructed the maids and bodyguards not to be too strict with him.
Ryan isn't stuck in the dungeon all day,if the bodyguards were watching him non-stop, he wouldn't be able to sneak into Alice's bed.
During the day, he's pretty free to roam around the villa, except for Alice's room on the second floor.
At night, though, he's locked up in the dungeon to sleep, and the door doesn't open until 8 AM.
After bringing him here, Alice doesn't really keep tabs on him, but he has to show up for breakfast and dinner, or he won't get to eat.
After breakfast, Alice usually heads out, and until she returns in the evening, Ryan can do whatever he wants.
The maids and bodyguards take good care of him, fulfilling most of his needs.
