Confused by my manager's behaviour

Hello my manager is a woman. I have 4 to 5 examples to share. Whenever she notices me helping some female colleagues she starts getting restless maybe. I see her ears or attention focused and seeing me repeatedly like for a microsecond all in a tightened look. This has happened with female who are there from even before her to those who are freshers. She directly tells me don't help her. Why are you giving her so much help. Then she starts uttering in hindi these lines. Kon thi. Utna karne ki koi jaroorat nhi h. She's not a hindi speaker while I am by the way. Now I have never noticed this when I am giving any guidance to other boys. She seems to be overjoyed probably. What's going on. Am I overthinking? Is there anyone who has experienced their manager behaving this way?
