Peter finds himself infatuated with a beautiful girl at the club. She's got everything he's ever wanted. Now he just needs to build up the courage to ask her out. He comes close a few times, but his anxiety gets the better of him. It isn't until she's walking out that he realizes he'll never get another chance, so he follows her home, trying to catch up while building up that necessary courage.
Then she turns and walks into a familiar apartment building: Dave's building. Dave is Peter's long-time best friend and he lives in the garden-level suite around back. So Peter slips around back, hoping his friend is still up. And that's when he sees the beautiful girl from the club in Dave's living room window.
