Looking at those letters felt a bit strange to Ryuutaro as well. He didn't know a lot about the past, obviously he was one for looking ahead, but every single line just seemed angry to him. He imagined Hayato's hands carving it, the way they'd looked back then.

For a moment he lost himself into his imagination of what the past might have been like, then he turned his head to the Hayato of the present.

"I can imagine...", he smiled softly. Maybe it was a slight bit, like when they passed the places he'd been at after leaving home on their visit there.
