Just to keep Suman happy.
Vividha is ready to tell the truth.
Sujatha also wants to be free with Atharv.
But Ravish wants them to play drama for some more time. They are all oblliging him because he is helpful and a good person.
When suman will be ready to hear the truth? By the way she talks and behaves, she will never be ready.
So Vividha has to play and so the others.
Ravish cares only for his mother but not others. Vividha cant be with Atharv. Sujatha has to listen to him.
And Ravish is not talking about army or joining duty. He is permanently here to make Suman happy. And make others feel guilty and obliged to him
