Nagi often felt troubled in situations such as when he couldn't beat a certain level in one of his mobile games-- or when he was lacking motivation in football, or when he had to actually get up and out of bed to do things.
But Nagi had never felt as troubled as he was right now-- watching as you and Reo talked and yapped to each other as if you had known each other your entire lives! A visible frown crossed the boy's face, a sour expression imprinting on his face. You and Reo were pulling a prank on Nagi: though, the boy himself didn't know that, too fueled by his own jealousy to notice the way you two were over-exaggerating things.
You and Reo had decided to try and make Nagi jealous of the purple-haired boy, just to see how he would react when his best friend was acting all buddy-buddy with his lovely girlfriend. Reo slung an arm over your shoulder as you rambled about random topics, and Nagi felt his irritation and jealousy grow.
"Reo.." Nagi breathed, grumbling as he stalked towards you two.
