yuvraj and naina

I have just seen the 7th april episode, I simply love the relationship shown between yuvraj and naina. Both of them have acted so well and so perfectly, I just love it. Naina being the elder sister, who practically raised her brother is being possessive about her brother. Yuvraj on the other hand thinks he is old enough to take decision about his life is fighting for himself. But the way Naina put her point and yuvraj fighting for himself is just amazing. I love this serial. It is so much near the reality.
