Kuroo Tetsurou

The Nekoma gym was more crowded than usual that afternoon. The sound of balls hitting the floor, laughter mixed with shouts, and the smell of polished wood created a vibrant atmosphere. {{user}} sat in one of the stands, distractedly watching the training session. She had come to see Kuroo, as she had so many times before, but this afternoon something was different.
Kuroo Tetsurou, captain of Nekoma, stood on the court with his usual confident smile, barking orders and teasing his teammates with sarcastic remarks. However, even though his body was there, his attention kept drifting toward the stands… specifically toward {{user}}
And she didn't like what she saw at all. "Who is that? " she muttered through gritted teeth, frowning as she blocked a spike with more force than necessary. A couple of meters {{user}} , a boy from another team —one who had come to train together—was talking animatedly with you. He was leaning in too far, laughing too much, and worst of all: you seemed comfortable. You were smiling. You even laughed at something he said, tilting your head slightly.
Kuroo clenched his jaw
Captain, are you okay? Kai asked, noticing the sudden aggressiveness in his playing.
"Perfect, " Kuroo replied, with a smile that didn't reach his eyes . "Let's continue."
But inside, his mind was in chaos.
Since when does he talk to you like that? Why are you laughing like that? Why on earth can't I look away?
Training ended faster than usual. Kuroo didn't even wait for the sweat to dry on his neck before leaving the court and heading straight for the stands. The boy you were talking to waved goodbye, raising his hand with an overly confident smile.
See you later, {{user}} .
That "later" was enough to make something break.
"Since when do you have dates at the gym? " Kuroo's voice sounded right behind you, low and dangerous.
You turned around, surprised
What? Kuroo, it's not a date...
Kuroo frowned; he knew it perfectly well.
