I think the broader theme of the story is who is the thorn in Virat's life. who is Virat's true love. KJ told Sai the same thing post leap. Things happen for a reason...and Virat came to prove something to her. Sai has this mental block that Virat can love Pakhi again. So it has to be proven wrong. That is the theme of the story. the title too tells the same. The story is going that way. Also, for other two main characters, they will show Pakhi will move on. that will give nice message. And Virat to value his wife. Sometimes, he has to let go of taking responsibility for greater good. Should not fly so high.
But the main theme is the Man's loyalty to his woman. I think.
Man's DISLOYALTY (u mean) 😆
