If Kunal Bri or Adi told Ram about Vedika’s intentions he will go into complete denial, anger & block them. We already got a preview when Adi tried to tell him that his closeness with Vedika is unbecoming. So his friends remaining quiet so far is justified.
The only difference is now Ram knows he loves Priya, not Vedika. So I think his friends should try now. Worst case he will still get mad & block them, but at least it will plant a seed of doubt or caution in his mind and he will start seeing Vedika’s behaviour in a new light.
