Drooling on your table, you slept dreaming about your favorite food. Kiriyu watched you slobber over your wrapped around arms.
"Uuuuh, (Y/N)?" He called to you several times.
You woke from your slumber feeling the cold sliva running down your face. Immediately, you wiped your face throughly in embarrassment. A couple other classmates giggled in amusement.
The teacher was talking boringly, so you scribbled in your side journal. He reminded you of a main anime character that was stuck in another lecture. Though, you would be the main character in this situation.
----later
After a lame amount of time, your favorite period finally came; lunch. You created a large dish to share with Kiriyu. You would sweep him of his feet with this meal. (If lunch isn't your favorite period of school, just imagine it is for this situation.)
You joined Kiriyu at the glorious roof. He sat prepared to taste a delicious meal from his close one. You took out a big black box lunch. The nice fumes unraveled along with the food.
But just before you could open the box to both of your chopsticks, Saiyo flew by with swift hands. He whipped up the food with one hand, and smirked viciously.
Attempting to steal it back, you jumped back and forth trying to reach the now sky high lunch. Saiyo lifted the box all the way up in the air. With the addition of his tall height, it was almost impossible to reach you yummies!
"Give it back!" You hissed. Anger surpressed in you; A.K.A ain't nobody gonna steal my food and get away with it.
Saiyo shook his head with a gleaming smile. He chuckled at your struggle, and even tried to tickle you at one point.
Kiriyu stood back, confused. He glanced from you to him curiously. Hmmm? He observed you both quietly.
"Stop it already, Saiyo! You know this is unfair!" You furrowed you eyebrows in frustration. Why wouldn't your brother give up already?!
"Nope not yet :3" He teased. He obviously wasn't giving up.You decided to rake matters to extremes.
"I didn't want to do this, but you leave me no choice!" You warned with a glare.
Your foot stomped on top of his toe and the tip of your elbow curved into his stomach. With a sharp jab in the gut, your brother dropped the box. It fell into Kiriyu's arms.
Agonizing pain would be the only thing Saiyo could feel down below. His cowering head was just enough evidence to prove so.
You swished your hips at him in a mean pattern. He had gotten on your nerves, especially today!
"I'm not playing with you!" You locked yourself in Kiriyu's arms, and dreaded off.
When nothing appeared to be near, Saiyo laughed himself off. He laughed a hysterical rythmn with a large smirk. He twitched his fingers around. Thinking up a new plan.
