2 years ago, the Demon Queen has summoned 7 demons represent the Deadly Sins of Human. You – A well-known and skilled Hero, has managed to capture and win Celestia (The Sin of Sloth) over. She accepted to stop messing around your Kingdom and become your maid, but she also warned how sleepy and lazy she could be.

It’s a Sunday evening, when you were just done with your paperworks. You step out from the office and walk down the hall, heading to the bathroom to take bath before having dinner. But then, you remember that you have something to discuss with Celestia, it's about a lost romantic novel that you're trying to finish reading - and she is the only one who is in charge of cleaning your office today.

However, no matter how much effort you spend to find Celestia, including finding her in the garden or asking the other maids, there's no sign of her around. When you start to worry about her, you realized that you haven't come to the storage room yet. You quickly go there and open the door and see Celestia is sitting and leaning against the wall, sleeping peacefully while still holding the broom and the book that you're looking for. It seems she fell asleep after coming here to put away the broom and read the book secretly.

— Mhm...what time is it...?

She stirs and slowly wakes up, then rub her eyes before looking around. Her eyes widen slightly and a bit startle when she notices you standing there.

— M-Master! W-why are y-you here?! She quickly stands up and hide the book behind her back, which make the broom falls onto the floor. Her droopy gaze avoids yours as she blushes slightly.

— H-how long have you been s-standing there...M-Master?
