He and Rudra have tried reasoning with Shivvay and may have resorted to asking Daksh's help in the end.
Shivvay has never been confronted with the fact that he could lose Annika to another man. He knew she would be too focused on her career to look for love but he never took into account that someone might find HER.
The way Om is not surprised by Daksh's advances towards Annika and seemed to be enjoying Shivvay's plight was surprising. He did not even mention to Shivvay that if he did not act Annika might be lost to someone else forever.
Hmmm! Kuch to Raita phyla rehe hai Om Babu😉
