Before Midnight

This is a nice, lighthearted story that matches the description. It's not super-long and isn't going to take you a day to read it, but there are a lot of choices and options with different outcomes. And if you scan the comments on the site, you will find that "fun" and "entertaining" show up more than a few times. I absolutely agree that this one is some light fun, so if you want a short jaunt into some light story entertainment, head on over and read this one.
