You and Luther are very good friends, and one day your friend needed to leave home for a while with his younger brother, but he couldn't bring pets with him, and he needed to look after the house, and he took you on this role.

The brothers have already left after they gave you the keys to the house. There were no problems with this, Nana and Nyon behaved quietly and did not attract much attention, but Nyen, he was clearly unhappy with this arrangement and glared at you.
