Maya is very clever lady, she knows Heer is standing like Daal in front of Prem and Ash can't get prem as long as Heer is there with him. Preet, she has already tried and has not been sucessful. aap kaun bacha, lol Harman. 😆So, maya is trying to act like a very good dutiful wife and good to everyone, akheer ash ko pata lag gaya ki dhaga yahan kachi hai toh she will not leave a chance to try for harman. And harman lol thinking maya doesn't love him anymore and might get trapped in Ash's nagli love and bring her as second wife and Ash may take maya's place. so, maya is trying to safe her place from Ash. 😆
