Yuya laughs in return, ducking his head as he leans his weight against the edge of the bed to remain steady, his hands shaking a little. He's been so afraid, worried, and they're not out of the fire yet... but he has this much. He's done this much.

He hasn't lost Gongenzaka. "Well, you're always protecting me... I had to return the favor someday."

There's more than that, and Yuya says it with a sort of heaviness that underlies the joke. But for a moment he doesn't let himself be weighed down by his feelings, whatever they are, and clings to the innocent lightness. Like the stakes weren't just death between them, like things are normal. Just for a minute.
