Ava is the sister of Rasta, played by Yekta Nasser.Although she has shown throughout the series that she is a really compassionate and kind sister, it is not unlikely that her behavior will be just a mask on her face. Maybe for any reason he is jealous of his sister.
Maybe he had plans for himself that Arash and Rasta’s marriage would ruin, maybe he was disappointed in the meantime.
Ava was one of the few people who knew the time and place of her sister’s presence on the wedding night, and even the parents of the bride and groom did not have the hairdresser’s address.
So it is possible that Ava hired someone against her sister. If that happened then we would all be in for a rude awakening.
We all know that Turan, played by Nasrin Moghanloo, was against the marriage of Arash and Rasta from the very beginning, but did he draw such a criminal plan to prevent this connection?
This seems a little unlikely.Because if it turns out that everything is under Turan, then the audience of the series will not be surprised and nothing special will happen.
So the end of the series will not be so surprising, but he is also one of the suspects.
