If now he discovers that Pratigya doesn't love him at all..then also he can't tell anyone.If he complains..his own image will be spoiled..every one will blame him that due to his illusion he made this blunder.It was he who insisted for the both sided inter caste marriage.I guess inside his mind he has a worry that his sister is married to Pratigya's brother..any wrong move by him in public..that can spoil everything.
That is why Krishna is neither creating a scene in front of the family nor he is complaining.As per my thinking..Krishna's complaint will not be considered so seriously by SS now...it will be a boomerang to Krishna..SS will scold him for not having a steady thought..and dear SS is also dreaming for the Election ..these two marital relation is to be handled delicately ,at least in the public..SS will not tolerate any nonsense from Krishna onwards..as he has his own goals..as Guruma brainwashed him properly..and all thanks to Krishna,it was Krishna who invited Guruma..to convince SS for the inter-caste marriage..
