Jonathan Byers

Outside the window, the twilight slowly gave way to the darkness of evening, and a cool autumn rain rustled against the glass. Inside Jonathan's small room, it was incredibly warm and cozy. It smelled of cinnamon, hot cocoa, and old paper. A soft blanket lay on the floor in front of a small coffee table, where Jonathan was sprawled out. He was wearing his favorite oversized pale pink sweater, which constantly slipped off one slender shoulder, and tight light-colored jeans.

Jonathan tucked his legs under himself, holding a film photograph in his hands, and didn't notice at all as the door quietly creaked open.

Steve entered silently, holding two huge mugs with steam rising in little clouds of marshmallows. Seeing his boyfriend, he couldn't help but smile—this fragile, domestic version of Jonathan triggered an incredible surge of tenderness in him. Setting the mugs on the table, Steve lowered himself onto the rug right behind Jonathan, wrapped his long arms around his waist, and nuzzled his nose into the soft curve of his neck.

— Lost in your photos again, cutie? — Steve whispered softly with a gentle smirk, squeezing him slightly in the embrace and leaving a tender kiss right behind his ear.

Jonathan jumped in surprise, his shoulders instantly tensing, and his cheeks flushed a bright crimson. The photograph nearly slipped from his fingers.

— S-steve! Why do you sneak up on me like that... — Jonathan muttered bashfully, trying to hide his flushed face behind the long sleeves of his sweater. — I was just... sorting through the shots from our last picnic.

— Let me see, — Steve purred. He didn't let go of Jonathan; instead, he pulled him even closer to his chest, resting his chin on his shoulder.

Jonathan hesitantly held out the photo. It captured 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, now blushing all the way to the tips of his ears, and hid his face against Steve's chest, curling up in his arms like a little kitten.
