A girl can dream. But I'm trying to avoid the precap..suman is extremely orthodox
Her views have always been progressive with Rishita but not with Raavi. She definitely sees each bahu in a different light and treats them differently.
I won't say she is orthodox, she is nowhere near orthodox, just has to show that she is Maha Saas and her mood depends on how Shiva feels and treats Raavi accordingly.
If he is not happy with Raavi, even if it is his mistake, then again Raavi has to bear the brunt of Suman's anger because her son is unhappy.
