he opened the door for her

The fact that he got down to open the door was so sweet and couply... even she was surprised..

now when i see the promo makes sense.. shaurya has realised he loves her or atleast is attracted to her.. and she isnt a student anymore (hence dont call me sir)

I think Shaurya has been itching to open a door for her for a long long time. He got almost giddy to open the door for her. It was so cute. I think him wanted to do something like that for her sprouted because of Ahir like when Anokhi coughed and he wanted to give her water but Ahir beat him to it. He walso wanted to somehow comfort Anokhi when she was scared after identifying the kidnappers but again Ahir beat him to it. He wants to subconsciously do these kinda small things for her and it's honestly so sweet. He even got so grumpy when Ahir beat him for the pen. The dude literally threw the pen back. Cutie

After the way Anokhi scolded him for kidnapping her like goons, he wanted to prove he is Mr. Gentleman. So sweet of him.
