She did mention that loving the wrong person was Suman's mistake .
Whether she was referring to the guy's character (already married) or the guy's age (he was significantly older to Suman), I'm not sure......
I think she was just referring to the character. Idk why but I feel she is not that judgemental about age gap atleast not as obsessed as HP is. Not that she wouldn't have a problem with ViDev but I think she will understand. She was also never shown being harsh towards Neeli
