It has been made clear from almost the beginning that Arjun is here to deceive Sam , to extract his revenge for whatever wrong doings Sam or her father has done. The path that Arjun has chosen for his revenge is to get close to Sam, make her fall in love with him, alienate her from her friends and family and then leave her... hence Sam and Arjun Track began .The possible tracks at this point in time are Arjun actually caring for Sam and eventually falling for her or him falling for Radhika , his complete opposite, her innocence, positivity & simplicity winning over his arrogance and soothing his pain.
Both the tracks are well known and have been explored many a times in the past. Which track would the CV's chose is not certain yet however what is certain is a deep friendship between Radhika and Arjun and for this friendship they both need to bond, spend time together, understand each other, support and stand up for each other and as audience and fans of this show , we should give these characters time to bond and build rapport.
