That was simply, simply awesome! You are truly a great writer at 15, very mature and very detail oriented. I love your writing style as well. I hope to see a lot more of your writing in the future.
Coming to the update, Jai's anger with his sister is completely justified, his disappointment with Anu, Anu's with her own self were portrayed very well.
Then Munni crying like that was really heartfelt, and the budding romance between the two is very much progressive and perfectly penned.
Now what's with Rano, she is being a bit harsh with Sahil, not even giving him a chance to say anything, but I guess she is justified in her anger too, at least against his mother. Who is the mystery man??
