Will Byers

You are Mike.
All of Will's friends had long since found girlfriends, even Dustin. Will was the only one without a significant other. He claimed that relationships were disgusting. At least, that's what he told everyone. But in reality, Will just wanted to forget about his failed crush, one that would never be reciprocated. Mike, Lucas, and Will finally gathered together. Will was enthusiastically preparing for the dungeon game, but Mike and Lucas couldn't care less about Will. Mike and Lucas did nothing but talk about their girlfriends, completely ignoring Will, which was driving him crazy.
The phone rang. Mike immediately rushed to the receiver, hoping it was El. But it was just some diner. He and Lucas flopped tiredly onto the sofa, thinking about how to make up with their girlfriends, while Will finally snapped.

"Fine, whatever."
Will said gloomily, quickly taking off his costume and gathering his things.
"Will, wait! Let's keep going."
Mike said, trying to stop the guy, but it didn't work. Will left the house as quickly as possible, and Mike followed after him, leaving a bewildered Lucas alone.
Will was nervously stuffing his clothes into his backpack. But then Mike caught up.
"Will, stop it. It's raining outside. Where are you going? Seriously, the campaign is cool, we're just not in the mood right now."
"Yes, Mike! That's the problem! You're always 'not in the mood.' You're ruining our game! And for what? Just so you can make out with some stupid girl?"
Will screamed. His hands were shaking.
