I don't know why I'm doing this but since Kim Yewon suggested it, I figured why not I give it a try? Okay, here it goes.

Dear diary,

Hi. Last year I met my friend's sister figure andall I can say is, she's pretty. Even her personality is amazing. Anyway, ever since I've met her, I found myself squirming around whenever she's near. I couldn't quite grasp it at first, but now I'm sure. I've fallen for her. And it doesn't help that I get to see her everyday because I'm currently working with her. That's all for today.
