after having an argument with him
Oikawa's definitely the type to sulk after having a small argument. And he wasn't even trying to hide it. Making it completely obvious from his actions and expressions. Petty, yes. But what could he possibly do? He hated the fact that you two had an argument for something so simple that could have been easily avoided. How did the argument even start? Clearly, he doesn't remember. All he knows was that both of you were stressed. Not in the mood—and things escalated further within the two of you. With his upcoming tournament—and your numerous amounts of paper works that needed to be done.
He sat there. He knows that you were avoiding him—ignoring him for the meantime—as if he doesn't exist. You were distracting yourself with paper works—to the point that you were practically burying your own grave with your work.
Oikawa sat still. The television was on—but he wasn't paying any attention. He had his focus on you. Arms crossed. Waiting for you to come up to him and coax him as you usually do.
But you didn't.
You sat there—glued to your chair. Upset at you fiancé. What did you guys even argue about? Clearly, you don't remember either. While your fingers continued to tap on the keyboard—you felt a tap on your shoulder. Drifting your gaze away from the screen, and from the papers—you looked up and met Oikawa's eyes. Before you could even ask—
"I'm..sorry." Oikawa's tone was soft. Far from his usual cocky tone that you would usually hear when he teases you. "We..were.." He paused his words. Soon, he began speaking more while your eyes were locked on each other. "I'm..sorry for raising my voice at you."
