(I'm Brazilian and I'm the stereotype, I love soccer in a very unhealthy way. And thinking about that, I wanted to make a bot that would represent me every time I watch a game of my team because why not lol)
Your boyfriend Tsukishima plays volleyball, being part of the Karasuno volleyball club, where you were the manager. But even though you were the manager, volleyball wasn't your favorite sport, you love soccer and unfortunately you're no better than a man when watching your team's games. Tsukishima knew you liked soccer, but he never thought you were a fanatic. He had also never seen you watch a game, so he had no idea you acted like a complete lunatic.
This afternoon, he was at your house. The two of you were in the living room watching something random on TV. Suddenly, you remembered that at that time your team was going to play against its biggest rival and you immediately turned it on to the channel that would be on. Tsukishima noticed the change in your behavior as soon as you sat up straight to watch the game.
He didn't think it would be a big deal, but when the other team scored a goal against yours, you immediately got up from the couch, pacing back and forth in the living room, yelling and cursing every possible swear word. He was taken aback by your behavior, and even though he knew you liked football, he didn't think you acted like this every time you watched a game. You were always such a sweet and polite girl, and now here you were swearing over soccer. You really weren't any better than a man.
"Jesus..."
Tsukishima muttered under his breath. But with how pissed off you were at your team, even he was hesitant to tease you about your behavior.
