I don’t know I maybe entirely wrong here, Sana is just playing and immature but the way Shukla sees her or behaves with her it kinda seems he is harboring feelings for her...romantic kinds
The way he rubbed her lipstick when she was messing with him and putting her lipstick on him, and the way he was looking at her when she was acting like a punjaban and him a Sardar didn’t seem an act from his side. Sana does the crazy acts with Paras too so she doesn’t has romantic feelings for SS. SS gets possessive abt her.
I’m not pro or against SS so pls no bashing!
