Shukla seems to have taken an interest in her.
I remember him being impressed with her in the secret room but nothing happened after that as there was so much SidRa drama and Madhu is obviously obsessed with Vishal.
But he does talk to her with a smile on his face many times. If she gave him bhaav he'll try to fake flirt with her too like he tried with Devo and Bagga. He does try to talk to her at times which is unlike him.
There is something about her that he does like. Maybe the fact that she doesn't give a damn about him and is obsessed with another guy. Maybe how she doesn't let things affect her and maintains a IDGAF attitude. Maybe she seems as insane as he deep down. But there is something different about the way he treats her.
It may not be romantic interest but he seems intrigued by her.
