Arjun?

Why is Arjun running behind Sam?

your dp is cute. ok apparently samairas dad samrat khanna had some short of relationship with nandini, arjuns only well wisher/guardian perhaps. well. cv did not revealed if samrat had any love interest on nandini or not. may be he used to treat nandani as friend. nandini thought it love and his gifted ring as marriage proposal. samrat refused to leave his family for nandini and she suffered from depression. she drowned herself in drinks. we still dont know if she is alive or not. so arjun want to take revenged from samrat using his daughter like he apparently used nandini.

its because he wants to get revenge on sams dad samrat, who he believes to have caused nandini, the only person who loved him/parental figure to commit suicide or something as samrat left her to stay with his family, which is sam and her mum. arjun was a orphan. so he wants to hurt samrat the same way he hurt nandini by doing the same to sam, and he almost did if it werent for radhika, causing doubt in sam after learning that arjun is up to know good, she doesnt know the full story but she see's that arjun is up to something where sam in concerned and doesn't want him to hurt sam, also sam broke up with arjun and doesnt want to see him, so radz has been trying to stop him. arjun had in the start wooed same into falling in love with him for his plan.
