So, to cut it all short, it is a mixture of Gupt (40%) and Pyar tune kya kiya (60%).
Pyar tune kya kiya:
There are so many similarities. It was clear from the start that Maya is not normal just like Urmila. She never liked Fardeen at first but then she fell in love with him as she got to know him just like Maya fell for Arjun. Fardeen never told Urmila that he was married and his character is quite similar to Arjun's. Honestly, it became crystal clear when Maya became his model (same as Urmila became Fardeen's) but at the end she found out Fardeen was married to his friend (I dont remember her name). There is only one direction where this can go- Maya committing some horrible crimes on her way to get Arjun, Saanjh disclosing the real truth and Maya madam ending in Asylum.
Gupt:
This is the second storyline. Promos showed that Maya and arjun went to this pandit who said their married life would be difficult which made me think if they are going to fall in love then this storyline points towards Gupt movie where Bobby loved Kajol but she being all insecure and jealous tried to kill Manisha and hence in a fight scene she died. I think this storyline would be better for this serial as I really dont want Maya as villain.
Conclusion: Honestly, I think director is still deciding the direction of this serial and he is basing it on how much we like Maya and Arjun. They will easily change the storyline based on our reviews and opinions. If fans love Maya and Arjun more than Saajh and Arjun then it is going "Gupt" way or else "PTKK".
Spoiler ahead
I saw this promo thing where Maya proposed to Arjun but he rejected. So, maya threatened to kill him and herself if he says no so he asks for some time to think about it. I really think this is going "PTKK" because urmila also threatened Fardeen that if he doesnt stay with her she is going to jump off the roof. Director is taking a lot of cues from this movie. Anyways, let me know what you guys think about it. Peace!!
