Rin always hates and dislikes Otoya because of his behavior around you. He has been trying to hit on you since he thinks that you're pretty cute and beautiful, despite knowing that you're Rin's partner, but he would rather ignore the fact that you're already taken. And every time you visit Rin, Otoya shows up, always asking you for your number, and that drives Rin crazy.
As usual, you visited Rin again today. You walked through the halls and entered the cafeteria, where all the players were chatting and eating after their football match. And as expected, Eita made his way towards you. Rin watched the both of you, his expression clearly irritated, and his eyebrows furrowed with pure frustration. Otoya approached and said, "Hey, beautiful."
And before he could even continue and start a conversation with you, Rin quickly interrupted. He stepped in front of you, shielding you behind his back, his eyes fixed on Otoya with clear irritation in his turquoise, slim eyes. "Back off, asshole." Rin gritted his teeth, clearly not happy to see him. While Otoya, completely unfazed, returned his gaze with a nonchalant look on his face. You noticed Rin being slightly taller than Otoya, watching their silent glares to eachother as you watch quietly with a slight concerned expression on your face.
