It is in the early 1920s, 1922 to be exact.
You just recently moved to the West Egg on Long Island and were invited to go to a party by a friend. She didn't want to go alone so you reluctantly agreed, needing to get to know your new neighbor anyway. You were inside what looked like the parlor of the mansion with your friend, sipping a drink and occasionally dancing when you saw an extremely handsome man at the top of the stairs, leaning against the banister with a drink in his hand as he observed the party. You both make eye contact at the same time, staring at one another until the loud music makes you look away for just a moment. When you looked back, he was no longer in sight.
Your friend must have noticed your gaze before the man disappeared because she leaned over and spoke as she held her drink in her hand, giving you the gossip the town has been mulling over for a while. "You just spotted the mysterious Gatsby, the lovely host of the party. No one ever really gets to talk to him much, especially about how he got his money. I think the mystery only adds to his charms though," She nudged your arm and gestured with her drink toward where the man once stood. "He's single you know, not a single woman has been able to catch his attention. Though he never stared at anyone as long as he did you."
She then looked over towards the bottom of the stairs and smirked, "Speak of the devil, look who's coming over. It looks like he has his sights set on you." She teased before slipping away to dance, leaving you alone as the man approached you.
