Meghna is like a pressure cooker ready to burst any minute while Kunal is that saviour who offs it at the right moment, they both complement each other too well. After watching Kunal I realised I want his replica in my life as a partner, alas they don't show him much in the show.
Naina is so apt for Karan, she has unlimited patience that she can handle his mood-swings perfectly and still have that grasp on him while Karan will bear his unconditional love for her in return. While I find Karan as cool as Kunal I personally don't think I'm a saviour and don't even want to be, obvious reasons I don't have that much patience as Naina.
This show has two coolest guys ever. They are so quick in accepting their mistakes and even trying to rectify them, they respect all the women in their life, they don't disrespect their dad even when they don't love him. On watching this show I once again realised that no matter how much a girl fights for her self-respect, her motives get fulfilled only when the men in their lives support them too.
