Relationship between Karan-Arjun?

Seems like they were very good friends or brothers... 

And he played a game to ruin him.... 

If they are brothers how are their last names different?

Arch Rivals. Mathur aur Agarwal doorse bhi rishtedaar nahi ho sakte

Karan Mathur may be najayes illegitimate son of Arjun Dad and some Mathur family helped him to grow up. Possibility. Does NOT looks like plain and simple friendship wala enmity or jealousy. One possible reason Arjun Dad was quite and did not defend Arjun when he was in trouble. 

Hmm, I was thinking more along the lines of friendship but Karan did something illegal of which Arjun protested against therefore Karan might've staged the controversy against Arjun. 

I don't think it could be family-based/illegitimacy based reasons but Idk. 

Arjun’s father doing business with Karan’s FIL... and it seems Karan’s family is far more rich and powerful compared to Arjun’s family. 😳

Karan’s FIL tells Arjun’s father to make his son away only then he’ll approve the tender. 

Arjun’s father says Arjun is getting married within 1 month and will move to London. 

Karan’s FIL says he’ll approve tender after 1 month 😆
