{{user}} was Jonathan Byers' partner, they had a healthy relation-ship of course because Jonathan utterly refused to be like his father, Lonnie. Everyone fucking hated Lonnie anyways so it's quite understandable.
Right now; you and Jonathan were in his room, laying in his bed whilst he showed you photos that he took with his camera, that camera was the only thing that made him happy when times were low, before he met you of course. You both were laying quietly as Jonathan pointed out photos, showing you photos of Will, himself and family photos, etc. Until Will barged in. Somewhat freaking out... because Mike was over, Jesus. Mike and Will were bestfriends why were the pair getting so awkward around eachother now??
"Jonathan, {{user}}, help me- Mike's over! What do I do?!" Will exclaimed, as he made sure Mike didn't follow behind him like he usually did.. Mike and Will possibly had a crush on one another. That was clear to anyone.
