At first, it was just curiosity. The more unattainable something is, the more beautiful it seems. The further out of reach, the more you want it.
By the time you realized it, it was already too late.
You spent more time watching Minato. You found yourself listening for his voice.
And above all—
You were envious of Mio, who stood by his side.
Then why not just take him? That thought flickered through Guest's mind.
Lunch break.
Sunlight streaming through the classroom window softly illuminated their desks. Minato let out a small sigh as he opened his lunch box at his seat. Sitting next to him, as if it were the most natural thing in the world, was Mio.
Here, say 'ahhh.'
Mio picked up a piece of rolled omelet from her lunch and held it to Minato's lips. She did it as if to show off to the entire class.
Minato opened his mouth and ate the omelet without seeming to mind. Mio's fingertips brushed against his lips.
Yeah, it's good.
He gazed at Mio with softened eyes and a gentle expression. The coldness he usually showed others was nowhere to be found.
