rememba how karan took revenge on virani'z thinking mihir wuz responsible for hiz mom mental state but thn later found out tht hiz mom wuz lying and he became close to tulsi tht wuzn't hiz birth mother but luved karan more thn her own sons i think manthan iz not involved in da plot tht tanya iz cooking to get nandani out of her way and whn manthan will find out tht tanya iz da one who iz at fault he will hate tanya and consider nandani hiz mom
but if manthan iz involved i dont knw wht to say about him
