Simple Kual (Gulabo) was perhaps looking only for a short-term role in TMKOC, therefore it is understandable for the writers to get her married off to Mohan who is neither a permanent member.
But any unmarried man in the audience who is above 30 years must be feeling the immense pain to see Popatlal's struggle to get married. More worse, sometimes some society members (especially men) make fun of him and still worse few members wants him to stay in that state his whole life. I think something is unreal and unwise about Popatlal not getting married. I hope the writers get some inspiration to get Popatlal married. It definitely will add more colours to the show.
