If directors are deliberately making the leads keep distance between them, it must be to copy the state of relation from KD where not even a hug has happened there. However Sairat have hugged and almost kissed few times, therefore maintaining the distance between the makes no sense. Maybe different directors are involved in sairat vs other scenes and the have different takes.
In precap, it looks like Sai has lost her eyesight and Virat is the walking stick. Director needs to be clear what they want to show.
See its natural that Pakhi will always want to stand next to Virat, so it's okay if they show her moving closer to him. But showing Virat going close to her, standing next to her should be avoided.
I dont want to blame actors coz they can't know how all this looks on camera. I will blame rest of the team, incl cameraman, director and person in charge of continuity.
People can justify actors, but I feel we shdnt justify the proximity shown between vamp and ML, coz then there will be no change. Virat wil and should be mindful of maintaining distance from Pakhi.
