Here is my take 😃
Past:
RK asked Unmarried Girl Madhu to Marry him because he wanted to Make Madhu's life hell as she slapped him
He wanted to revenge Madhu and blackmailed Madhu
Present:
Sultan asking Madhu to divorce RK to make RK's life hell.
He want to revenge RK and blackmailing Madhu.😕
If he had guts he should blackmail RK and not Madhu.
Past
RK told Madhu he hates her and thats why want to marry her to trouble her forcibly...
If you hate someone and you want to make their life horrible is understandable
Present
Sultan telling Madhu he Loves her thats why she should leaver her husband and come to him 😕
If you claim to love someone and you want to make their life horrible is 🤢
Regarding epi...I have full doubt on Mr.Joshi that he is Sultan's chamcha
And now I have full faith that RK knows everything 😃
