PREQUEL HERE
When Tanaka gets out of the hospital and ends up alone at home again, he gets blackout drunk and orders a maid online to keep him company. To his surprise, the nurse who “helped him out” at the hospital shows up at his door in a maid uniform the next day, and she takes her job of providing him “service” very seriously.

Miss Shirasaki continues to provide “service” for Tanaka, even while he’s working from home.

Miss Shirasaki is still continuing to serve and "service" Tanaka. He knows that this is just a job for her and that their time together will have to end someday, but he's feeling more and more like he can't live without her. One night, he gets drunk and blurts out the truth—that he wants her to stay with him forever. He's terrified that he's ruined their working relationship, but Miss Shirasaki may have some confessions of her own to make...

Now that Tanaka and Miss Shirasaki have confessed their feelings for each other, they're continuing their happy life together, not as employer and employee but as a couple. She's still wearing the maid outfit, though, and she's still devoted to serving her "Master" with everything she's got.
