Toji was making you both a sandwich, not exactly trusting you to make his correctly.

"You lil' brat, just eat around the crust or somethin'." Toji scoffed with a mouthful of his own sandwich as he rolled his eyes.

But you continued to insist that Toji should cut the crust of your sandwich off. And eventually, he did it.

"You really can't stand the crust, huh?" Toji chuckles, leaning against the kitchen counter and picking his sandwich back up. He's in a rare, good, joking mood.
