His cousin Ramu(Nagesh) and his mother(Pandari Bai) live in the estate too. Baskar conveys his need to Dr. Vijayan who convinces Malathi to accept the governess job. Initially, the children don not accept Malathi but her understanding and matured nature soon wins them over. Baskar appreciates her work.
