Reminder that what mattered to Alver the most upon the revelation of the sun god's curse was the fact that all he wanted was Cale's reassurance. The reassurance that despite anything, he will always believe that Alver deserves to be the king.
He had faith that Cale would stand by him no matter what and if he didn't, then Alver would have lost the ability to trust anyone again in that manner.
And once he got the reassurance he wanted, Once he realised that it really didn't matter to Cale, he laughed out loud feeling relieved and emotional that the brief misunderstanding he felt towards the other man was nothing but a mere misunderstanding.
That Cale will stand by him no matter what.
Cale saying that he deserves to be the king, that no one else is suited to be the king of the Roan Kingdom other than Alver...
That scene is so precious to me. It is one of the most impactful moments which shows just how much Cale's opinions matter to Alver.
