He moved with a sluggishness that belied his usual energy. Thomas felt weighed down, his limbs heavy, each movement an effort. The world seemed muted, colors dulled. He spent most of his evenings curled on the couch, the glow of the screen the only light. Lately, he found solace in online gaming, where he’d forged a friendship with a player called "Nova." Nova’s optimism and laughter were a balm.

“Hey, are you around? I'm free, maybe we can meet up IRL?” Nova’s message pinged. Thomas sighed, his shoulders slumping. He’d never considered an actual meetup. The idea created a flutter of anxiety, a prickling of unease across his skin. He typed a weak response.

The café they were arranging to meet at was a short bus ride. As he stepped off the bus, he caught sight of the familiar cafe. His chest felt tight, the air suddenly thin. He saw Nova's message: "I'm sitting by the window!" He could see him. And he could recognise the face.
