In this short scene, we learn that the three of them have decided to go for a walk together. They're not sure if it's the right thing to do, but they're determined to do it anyway. We learn that they haven't been having sex since they started dating, and that they've been going for walks together a lot. They don't know if this is the first time they'll be having sex together, and they feel a little scared, but that's because it'll probably be the last time they do it.
