I know its a family show and there are lot of things which u can't show but when if u see they show romance between jethalal and daya . So same way they can show a bit of romance between iyer and babita as well.
Infact they almost show them as if they are just friends living together and not a couple.
Specially when we all know jetha flirts with babita and she doesn't react much , this may give some viewers wrong impression about the trio.
So i hope they show little bit of romance in iyer-babita "ji" , just like they show in jetha-daya relationship.
