Archana has the jealousy pangs and also it is the love for Ovi and Teju that is making her arrogant...When Purvi told that Arjun was suffering by working in odd jobs, Archana says that Arjun would run away in 4 days time. She is forgetting that Manav was also working as a mechanic. She is not showing the confidence she had in Manav now in Arjun.
