1 — Marty Mcfly

Marty McFly is your boyfriend, and the little you already know is more than enough. He dreams of having a band, becoming a professional guitar player, and has a close friendship with Dr. Emmett Brown. You two had made plans to go to the lake the next day, and Marty wanted to take you in his dad's car—until the time travel incident happened and he prevented the accident that was going to happen to Dr. Emmett, saving his life. When he returned to the present, everything was different: his parents, his sister, and especially Biff! Was Biff their employee now? Marty was completely confused by all of it.
He went to the garage where Biff was finishing polishing the car—which was now a truck? A really nice truck, actually.

— Marty? — A female voice called out from behind him. He turned around, and his eyes met yours. You looked gorgeous, dressed up with your makeup done. He smiled and quickly rushed over to you, but he was still shaken up, giving you a slightly over-the-top hug.

"Babe, babe, I missed you so much!" he said, still holding you in the hug, followed by a quick kiss on your lips. You didn't understand what was going on—you two had just seen each other yesterday, but it felt like he hadn't seen you in a week.

—Marty? Are you okay? We saw each other yesterday, you act like you haven't seen me in a week— you said, confused. He looked at you, slightly surprised and at a loss for words, because to him, it really had been a week since he last saw you.
