from latest episode mehek seems to be not who just pester diya for property sake. even when his mom nitya bua told her so. As shown in ratan's rajyabhishek he said its ratan's right after his mama when mohak came forward for pagdgi ritual due to ratans bad health. so seem he may be possitive and supporting to diya
also he admires priya and help her and like yash he might have soft corner for priya and would fall for her or loving her secretly. in next coming epi's we may see both getting married too.
