sounds like amitabh's bhootnaath!!
Bhootu is about a girl name Pihu who dies in an accident and becomes a ghost but she longs for her mother.
She then befriends Kanha (young Lord Krishna) and he helps her make friend with a young lady Suchi who lives in the same house as Pihu (As after Pihu's death her parents left the house). Suchi at first gets terrified and irritated of Pihu but then slowly gets attached to her and then after an incident she starts seeing the ghost Pihu. The track now focuses of Suchi helping Pihu search for her mother.
It airs on Zee at 6;30pm and repeat at 11;30 pm
This story is interesting to see
there are some funny and interesting scenes of the child actors . for me I love to watch the child stars of this show they act too beautifully. Lord Kanha and Pihu's scenes are very beautiful and sweet and lovely
