Haria is an alcoholic and gambler person who abuses Raja as well as his whole family. He abuses him physically and verbally and also forces him to beg so that Haria can fulfil his needs through his earnings. His sister Sujju sells toys mainly ‘Firkies’ and earns something for her and her family’s living.

But Hariram forces her to give him all the money so that he can play gamble. Here Shanta and Sujata encourage Raja for education and to attend the local school. He also gets the admission but when Haria comes to know about his school going, he tears up his school-books and threatens him not to go to school. Raja likes to play with his friends and he always pretend to be the king which his father does not like in anyway and he beats him up. Very soon his mother and sister find out that Raja has lost his mind and really believes he is a king. He also refuses to listen and obey his elders.
