Kageyama x reader // Is this what they call love?

You're a 1st Year student at the Karasuno High School.
At first you were a good student, but with time you started loosing interest in school, and ended up in the same class as the tall guy with black hair and blue eyes.
"Tobio Kageyama was his name, I think",you said to yourself. Not that you cared anyways. You just wanted school to be over so you could go home and game. But for some reason that Tobio guy kept getting in your head after what he did for you that day.
Are you perhaps in love or are you just grateful for what he did?
