I don't see why Hariprasad has to dislike his sister just because she married someone older than her. I mean yes 20 years is excessive but many people of hari prasads age have age gaps upwards of 7-9 years in their marriage. People might be not accepting of it but it seems pretty weird to actively hate someone based on the age difference between their spouse. Would have made more sense if he was angry because she married by her own choice or something. Also hariprasad is a pathetic person and I hope the show doesnt try to whitewash his character by that thaka hara middle class baap trope and actually calls a spade a spade.
