I personally feel that if Sanyukta remains adamant about not accepting Tejal, Nikhilesh may get the couple get married with his blessings. Tejal can enter the Mazumdar household as a DIL and then get the right opportunity to prove what a gem of a person she is. It won't take long for Sanyukta to start liking and accept Tejal as the best choice for Aniket.
Sanyukta's real trouble will start with Monikangana, I guess.😃
