In reality, Mahendra is really busy, after seeing Aarav's confession he also wanted to confess her, but that time he wanted to give her, the dream house just like the pictures she posted on her vision board, and for Mihika, he really never tell or discuss little thing with other, and in the party, he talks with her just because he wanted to give a face to Sharmila and Sharmila tell her to give this job to her, she even has good qualification so he gets agree, he is thinking that in future if Aditi required a secretary then she will be best, yup he can feel that this girl is somewhat interested in him, but it is normal for him. So he really not cheating.
