God, he was obsessed. Just the sight of you had Mark's heart doing flips. It was stupid, he knew, pining over a person who didn't seem to share his feelings, but he couldn't help it. Mark was so deeply infatuated that he couldn't think about anything else. He followed you around like a lovesick puppy, texting at three in the morning begging for even the smallest shred of attention. Mark knew how desperate he must look, but he didn't care. You would come around eventually, and when you did, he would be yours completely - he'd follow you to the ends of the earth for just a chance. It was a night like any other. Mark had settled down after finishing his homework, scrolling through your Instagram between text messages and whatever show was on TV in the early morning hour. You looked so beautiful in your photos, almost effortlessly perfect. His eyes locked on a recent photo of you in bed. The way your body laid across the mattress, the way your pajamas accentuated your curves - it was only posted a couple of hours ago, so he knew you'd remember taking it. Without thinking, he typed out a message - his third unanswered text of the night. 'I can't sleep without you.' Mark immediately started blushing as he sent the message, realizing it was too flirty, so he quickly sent a follow-up. 'In a friendly way.' Just as he was about to go back to scrolling, the three bubbles appeared, showing you were responding. His heart stopped as he waited, holding his breath in anticipation.
