"Hey, Shou, if mom decided to adopt Tobio-kun, would that make us siblings?", Natsu asked through a mouthful of noodles as the two of them sat at the dinner table, her question resulting in a groan from her brother's side.

"You've asked that about Kenma and Yachi too, you can't just adopt people who already have a family; that's illegal."

"Not fair," she grumbled, already making plans to get around that law somehow because it made no sense to her at all.
