Sheesh..this is so wrong!
Firstly, Sam and Neil have been best friends, BEST FRIENDS from past 20 years, the closeness comes naturally. For Sam, Neil is the person she could depend on in every situation. There isn't anything vulgar in their relationship, and hugging each other, touching, and stuff are normal and a common thing these days.
Secondly, a misleading pic can't be a proof for something. Have you watched the episode? She had her arm around his waist in a hug like manner. Her hand wasn't under her shirt or something, please stop trying to demean NeSam's pure relationship.
Thirdly, there is no point in comparing ArDhika and NeSam. What Radhika did, that was just to irritate Arjun, and make him stop somehow from going to Lonavala. While NeSam and their closeness comes naturally after 20 long, very long years of friendship. And as per the current track, Sam needs someone to lean on after she had a break up, and what other option it could be than a best friend who knows everything about her?
So please stop making such posts.
