Observing that he wouldn't be left alone by the Gemheart clan heir, Orion was initially inclined to dismiss the proposal, as he had no reason to engage in any kind of battle, whether for fun or otherwise until he heard about the accompanying rewards.
Seeing Orion's contemplative expression from far below, Zephyrion quickly added, "If you're concerned about me keeping my promise, don't be. I stand here before everyone today, even in front of the King and the royal family, and I solemnly vow to Naka that I shall honour my promise, fulfilling it to the best of the Gemheart clan's abilities."
Not only Orion, but also the guests were taken aback by the Gemheart Clan Heir's desperation.
Regardless, after glancing at the King and Queen and seeing them nod in agreement, signifying that they bore witness to the Gemheart Clan heir's words, Orion saw no reason to decline Zephyrion's challenge.
