(Y/n) was a maid for the Sakamaki's for their whole childhood. Karlheinz found her and took her in and she became a maid. She became a maid for them at the age of 5. She always was nice to them, no matter what. She then had to leave to take care of the Mukamis while they grew up on Karlheinz's orders. What happens when she comes back to the Sakamakis?
