Hey, so I was neither a fan of Asim nor Siddharth, but in this fight , I think Asim is right.
Though his method of provoking is not. But it's more like a rubber band effect. Shukla's bullying got to him eventually and then he burst.
Also I don't feel the fight is because of Sana or himanshi's instigating their respective group leaders. Nor do I think it's because of Shefali.
It's simply because Shukla refuses to listen to others and friendship is a two way traffic.
Here's my analysis- Watch it carefully. Here I talk about Why I feel Asim is right.
