Arjun loves Purvi and betrayed Ovi
Pure love requires sacrifice
Pure love should make let arjun go with purvi
Pure love should see the other person's happiness
exactly...that is what ovi is doing...she understood now that arjun loves purvi...but she wants to see him happy...arjun can never have happy life with purvi, purvi can sacrifice him at any time for any stupid reason(except Ovi love)...
only thing Ovi is not understanding is Arjun is not for her love...
