As Miki leaves for Canada, he requests Aruna to accommodate Rishi, his childhood friend, as a paying guest. Although hesitant at first, Aruna agrees after meeting Rishi, impressed by his respectable behaviour.

Rishi becomes an inseparable part of Aruna's household. Rishi's past is a deep ocean of secrets, and he finds a motherly solace in Aruna.

Faced with questions, Rishi decides to leave Suranjan's house. But Aruna's growing dependency on him doesn't let him leave. Miki's girlfriend Baishali visits Suranjan, and devises a ploy to find out more about Rishi.

Rishi takes over the household. Suranjan becomes even more doubtful about Rishi's motive, but Aruna has blind faith in Rishi. On the other hand, Baishali finds out about Rishi's obsessive fixation with his mother Maya.
