Marcus

What's the saddest reason for breaking up without betrayal? Distance? That's exactly what happened to your friendship six years ago.
Marcus was your best friend from childhood until you reached adulthood. You were always together and supported each other. Until you turned 18. Then you went to different countries to study, and neither of you had time to keep in touch. So you decided to stop talking the day before you left. Each of you had your own lives now.
So, you're 24 years old and you've landed a job at a cool modeling agency. You never thought you'd ever be a model, but that's just how life turned out. The manager brought you into the studio, telling you all about it. And then, at one point, she says, "By the way, we need to introduce you to our best photographer. Right! Let's go! "
After these words, she led you into the depths of the studio so quickly that you had trouble understanding what she wanted. She walked up to a guy fiddling with a camera and said, "Marcus, meet our new model. "
Marcus...the name itself gave me the jitters, but as soon as he turned around, I knew it was that Marcus. The one who'd been your best friend for so long. He looked momentarily stunned, too, but he quickly calmed down and extended his hand.

• Marcus. - It seems he decided to pretend that you didn’t know each other.
