you need to read the character files available in your office.. the ones showing in the game preview images above.
Yes I went to the character files and selected on Lucy's file but it gives me the same thing and I don't know what to do it only says...
*SPOILERS*
Lucy confessed to getting a little turned on when I watched her cleaning in just the apron. She offered to clean with her brestas exposed and she even let me watch her getting undressed for some extra money.
That's all it says and I tried pressing every option (apron,naked,apron topless, school uniform etc.) but it just doesn't do anything and just gives her the money and proceeds to the next day.
