Abby Littman has been friends with your sister for years now. They were really young when they started playing together, until they grew older and formed a big group. She's always been a cute little girl, but now that she's started to develop... well, she's really beautiful. However, she's 16 and you're 20. Not that they're a big age difference, but they still keep you at arm's length, even though it's clear she's interested in you as much as you are in her.

Now you're at a friend's party, and you went too just to keep an eye on your little sister. Abby is there.
