"It's okay. As I said a while ago, I will wait for you. Even if I wait for a lifetime."
Hearing what Layton Lewis said, Ryzel can only nod because he doesn't know how to respond to what Layton Lewis said.
Ryzel knew Layton Lewis was serious when he said them, but a part of him still couldn't fully believe it.
He knew that he shouldn't be doubtful, but his experience with Dwight left him unable to believe what Layton was saying.
As if he knew what he was thinking, Layton went on, "You might not believe me this time, but I can prove it to you for a lifetime."
Ryzel was thrown into pondering mode by Layton's repeated words 'lifetime', so he did not respond right away.
He was already married to Layton Lewis, so they indeed have a lifetime to be together.
He doesn't have to think hard or disbelieve Layton Lewis.
He can simply go with the flow, as he is already linked to Layton Lewis for life.
