There is very remote chance that piyush disclosing something to Desai. As far a we know piyush seems to be a good person and he will keep his promise. The enty of a person from the main door is audible to krish. so Desai without taking risk met krish and told he forgot his purse and that is why he return back. The choice of room is suspicious. Why he choose meera's room?? Naturally he should use the third room where he is staying. If it is not meera, she can easily figure out some kind of action is taken place during her absence in her bed. I don't think they have enough time to make the bedsheets and other things  in the original state because they left the room immediately. So if it is not meera, she will definitely find out that some kinky action is taken place in her bedroom. If it is meera? Why she need to take a risk? Whole  night is available for her and can easily done this without knowing krish ( since rooms are sound proof). So less chance of meera. There is another chance that Nidhi might be the victim. Her recording are there in office computer and Desai can easily blackmail her and have fun. If it not meera, One think is sure desai is seeing other women as well. This can be a plan of desai, or since he is acting like a changed man, when he got an opportunity to have another women, he might have brought  her to krish home ( knowing  rooms are sound proof and meera is in office). We can not figure out anything as easily

Not only that, literally Desai and Meera left home for office they don't need to stay in home if they want to have sex. They can meet outside anywhere if the intent is to have sex with out Krish's knowledge. Its definitely not Meera and if it is then it is dumb to meet in the same house knowing Krish is in the house.
