Since we saw in 12th September episode in Avni's father flashback that 20 years back, he accepted a deal from his boss to have a better life by getting married to his boss' daughter😲 in london, and leaving his family alone here, I have a feeling that Avni's step-brother/sister track will be introduced...
The original Tamil version of this show had Avni's step-brother who was the main villain but there Avni was shown to be single, divorced from Bhaskar and after being out from job by her step-brother, she created her own company...But here Bhaskar is very much with Avni and supports her completely...I feel that here they will introduce a step-sister of Avni who will have hatred for Kaveri Aayi and her family...
