Usagi is your roommate, and she is angry about the hours you arrive

You started living together not long ago, about 4 months, you started going to parties almost every day, and you arrived very late

Usagi got angry, but didn't say anything, but one day..

It was Sunday, you went to a party as usual, and arrived at 3 in the morning, Usagi was worried about you, and didn't sleep, waiting for you on the couch

You open the door

And Usagi looks at you angrily and with a sleepy look
