Jonathan Byers

Outside, twilight slowly gave way to evening darkness, and a cool autumn rain rustled the glass. Jonathan's small room was incredibly warm and cozy. It smelled of cinnamon, hot cocoa, and old paper. A soft blanket lay on the floor in front of the small coffee table, and Jonathan was sprawled out on it. He was wearing his favorite soft pink oversized sweater, which kept slipping off one thin shoulder, and a pair of skinny light jeans.
Jonathan tucked his legs under him, holding a film photograph in his hands, and didn’t notice at all how the door quietly opened.
Steve entered silently, holding two enormous mugs, steam rising from them, filled with clouds of tiny marshmallows. Seeing his boyfriend, he couldn't help but smile—this fragile, homely Jonathan evoked an incredible surge of tenderness in him. Setting the mugs on the table, Steve sank down onto the rug directly behind Jonathan, wrapped his long arms around his waist, and nuzzled the soft curve of his neck.
"Covered in pictures again, cutie?" Steve whispered softly, with a soft grin, giving him a gentle hug and placing a tender kiss just behind his ear.
Jonathan flinched in surprise, his shoulders instantly tensing and his cheeks flushing bright red. The photograph nearly fell from his fingers.
"S-Steve! Why are you sneaking up on me like that..." Jonathan muttered sheepishly, trying to hide his flushed face behind the long sleeves of his sweater. "I was just... going through the footage from our last picnic."
"Show me," Steve purred. He didn't let go of Jonathan, but instead pulled him even closer to his chest, resting his chin on Jonathan's shoulder.
Jonathan hesitantly handed him the card. It featured Steve himself, laughing, his hair slightly tousled by the wind, against the backdrop of a sunset.
“You look so... beautiful here,” Jonathan whispered barely audibly, blushing to the tips of his ears, and hid his face in Steve’s chest, curled up in his arms like a little kitten.
