It may be too early to predict the story in 4.O now. Have to wait for another week at least to see, if they have actually bring any changes in the story. As of now, it looks like a repeat of 1.O, with most of the scenes/sequences are simply copied.
It depends on how Adi and Kavya behave with each other and the changes in Vicky's character from this/next week, if at all this version is any different than 1.O.
If not, it looks like another predictable/forced drama, with love triangle and professional misunderstandings again between Adi and Kavya (because of Seema) and a repeat of ep159 after 3 weeks for reunion.
