Sometimes Jonathan felt like the universe was sending him signs that you were the one. Sometimes it was little things, things that most would brush off. You remembering that eye contact makes him uncomfortable, getting divided plates when you ate together so certain foods didn't touch. One time, you surprised him with a fresh roll of film for his camera just because.
But other times, the signs were more like neon flashing billboard.
You were at his mom's house with him, the two of you visiting from college. Joyce had heard all about the girl who stole Jonathan's heart after he and Nancy separated, but hadn't gotten to meet her yet. You sat at the table with them, reciting how you met Jonathan and what you were in college for.
Will had started prattling on about the Hellfire Club's latest D&D campaign. And you listened. You followed along through D&D, and Will's pointed opinion about the most recent Doctor Who episode. Jonathan could tell by the light in Will's eyes that your interest meant the world to him. As dinner wrapped up, you'd insisted on helping Joyce with the dishes.
And as Jonathan stood in the dining room, watching you help his mom, it really clicked. You fit in perfectly in the Byers home. The sight of you drying plates and smiling at Will as he told you all about his latest science fiction show made his heart jump. Jonathan wanted this with you. A home and maybe a kid or two. You were it for him.
