Why Purvi has to see

Why Purvi has to see Arjun and Ovi hugging each other? Ovi can see Arjun-Purvi hugging or Purvi confessing her love. I think if Ovi sees Arjun first then Arjun will tell her he is in love with someone else. But if Ovi sees Arjun-Purvi together then there would be lot more room for misunderstandings. Ovi will be mad and not ready to listen what Arjun has to say then Manav, DK, Tej, Sachin all will be mad. Archana will be in bad spot. May Arjun and Ovi will not meet at the air port because arrival and departure terminals are separate. Purvi will confess her love then later see Arjun-Ovi together, and drama will start.
