Based on @koyuki-tan‘s “Peace Sign.”
“Masanori, what is this?” Hairu holds up a brilliantly fluffy, well-loved animal her son has hidden under his bed.
“Nothing,” Masanori says evasively.
“It looks like Brooke’s missing toy.”
Masanori pouts. “It’s not.”
“Masanori, are you lying?” Ui asks sternly, coming up behind Hairu.
Their child squeaks. “Yes.”
“Well, at least you admit it.” Ui sighs. “Hairu, can you call Brooke?”
“But I like otters! I wanna cuddle it!” Masanori grabs the animal.
“We can get you your own otter,” Hairu assures him. “But we don’t steal, Masanori.”
“Why?” Masanori frowns. “I wanted it more.”
“Are you sure?” Ui asks slowly. He’s never had someone ask why stealing is wrong before. He just assumed everyone knew that.
“Yes.” Masanori sticks out his lip.
Ui chuckles. “Then…then you could have asked Brooke. I’m sure she’d let you borrow it, but without asking she thought he’d vanished and she was very worried.”
“Oh.” Masanori looks concerned, to Ui’s relief. Maybe he is breaking through, after all.
Kids. They make him continually question morality.
