Hi
Since the maid is taking all the clients your best option is to level up the atelier searching ingredients. Like in previous months, if you reach a certain level (here's a hint, 12) an event will play that would unlock a way to turn things around (In the game over help corner, Olga mentions that you'll need someone's help) The maid is also is taking some of the ingredients so you might have to work more than usual. Also remember that doing the sex scenes gives you an exp boost
Hopefully you find this helpful
have fun
