Karan Veer Mehra being over possessive for Chum.

Since 2 weeks I noticed that Karan is being very much possessive for Chum , like whenever she used to talk to Shrutika or Vivian or anybody and when she used tell to Karan he used to show her how Shrutika and Vivian and not good for her or how Vivian is not deserving . And even in Ticket to Finale task for contender, it's good that he played for his friend but he should even allow Chum to play the task for herself. In frame task Chum always came first and Karan himself said that Chum is strongest in physical tasks. In the Ticket to Finale task between Chum and Vivian I think if Karan , Shilpa , Shrutika hadn't made Chum feel like that Vivian is being aggressive and she is being victimised I think that Chum would have played the task well without any chaos being created. For Karan it might seem he is protecting his friend but it's putting Chum to the back seat. And the love angle which they have why don't Karan openly confess it to Chum it just looks like that Karan thinks that Chum knows everything and there is no need for confession. When he hugs Chum sometimes Chum's expression are like that she needs to do this because otherwise if she makes a certain distance with it might weaken their friendship.
