EK DEEWANA THAT - psychiatrist murder and Vyon's father

I have just recently started watching the show.

So we see the first murder and its the psychiatrist who happens to be a good soul and wanted to help Sharanya but gets killed when he calls her in the middle of the night at the park where they were supposed to meet.

We see an unseen force killing him so that means it was not a human conspiracy but rather a ghost's doing. But we also know Shiv loved Sharanya (he sat by her bed holding her hands, got her her favorite flowers etc) so if the doctor truly wanted to help in making her remember the past, he should be the happiest. So why did he kill him?? My guess is that the doctor WAS NOT a good person. Sharanya is his new patient so it cant be that he really knew somthing about Kapali Hills. What I feel is that the doctor wanted to take advantage of her mental state and exploit her. Shiv got to know that and killed her. This is the most logical explanation right now.

Now about Vyom's dad, he seems to have also had a ond sided love thrust upon his wife. There is this dialogue by his wife, vyom's mom, that once you dad and son stop putting force into relationships, you two will get peace. So I feel like Vyom's dad did something similar to her like Vyom is doing for Sharanya. Or it could be worse. I do believe that Vyom is a positive character and after years of waiting,he is just not being able to give Sharanya the space she deserves. However, I think Vyom's dad has played some part in Shiv's death. I don't think Sharanya killed Shiv in the accident she did 5yrs back. I rather think that's how they started bonding. I think that Flower shop was Shiv's family business.
