It's good to see your updates back again...
I guess Nithila is trying to show her anger towards Selva by not following his advice and not asking for his help. Soon the business is going to go down....and Selva will have both marital problems and business problems to solve. Thanks to Nithila.
It's strange, because when they were both working in the Bangalore office, Nithila was shown to be the more intelligent one...while Selva kept singing "Magila, Magila, Magila" in his cabin. And when Nithila offered her advice to him then, he would openly reject it. Now their roles are reversed....
And I still have a feeling that something terribly bad is going to happen to Nithila...
