I think that maan will be attacked because of dev because of his extra goodness now imsagine if would not have made any attempt to search maan then why would pammi have attacked maan paami will make maan's' miserable till the time she manages to sell away KC she does not want maan to clam KC again hence she will not let maan get a job but once KC is sold she will not interfere in maan's work but dev is making it difficult for her by searching for maan so pammi had to attack maan so that she can sell away KC without any problem so indirectly is all dev's fault its because of his nosy nature maan will have a memory loss
