If u guys have noticed than from past few episodes virat had changed his approach towards pakhi , he no more go after pakhi to pacify her or sing best frnd song .
Virat is very well aware that pakhi is competing herself with sai , jealous of sai as he had pointed out these things.
Now even Virat as adapted a meethi churi approach towards pakhi , from past few episodes whenever pakhi questions virat or target Sai then he don't answer her rudely but still manage to shut her mouth up in his own way, thats why kaku & her mast gang don't scold virat when he answer pakhi as he don't sound insulting.
Pakhi is definitely not able to tolerate such behaviour from Virat , that's why in today's precap he was trying to instigate virat to get a harsh reaction out of him, so that she can make him guilty later for it & she gets his attention. As in precap she was targeting virat not sai .
