Warning spoilers

This is my first book I have read by Jenny Han. I've heard that she has a contemporary series called The summer I turned pretty. (is it good?) I totally recommend it if you are in to any contemporaries. Anyways, its about a girl named Lara Jean Covey. She's half Korean and half white. She has a little sister named Kitty and Margot. I absolutely love Kitty. She is so enthusiastic but sometimes stubborn. I thought it was Chris who mailed the letters but it was Kitty. WHHHAAT? I love Margot but why does she have to break up with Josh. I really like Josh. He treats Lara Jean pretty fairly. I imagine him as the nice guy. And unfortunently he finishes last. I can infer that in the next book, he will be chasing for Lara Jean. His emotions are pretty mixed up. He's crying for Margot and then Lara Jean. Why did he change? Didn't Lara Jean ignore you for a whole book? It kinda sucks though because we learn that his parents are fighting constantly. I'm starting to like Peter because he is so sweet to Lara Jean. It's probably because this whole book, I thought that he was going to be the bad guy and not the love interest. (Is it just me or I kept thinking about Divergent Peter?) Hopefully in the next book, I can see how this relationship carries out.
