I'm someone that has read the novel so let me explain!!
A lesha is basically a harem meant for the Shah's (mainly meant to be amon's harem)
The reason why it's bad of Rue to become a lesha and why Na-in is mad isn't because he sees Rue as a competitor in the harem for amon,, but rather because it is the Lesha's duty to die for the Shah's. And it is the duty of one of the Lesha's to die before any of the ceremonies/celebrations that are being held.
Nain is upset because Rue is misunderstanding why Na-in is so upset at everything happening around him and sees it as "I've upset nain, time to find a way to die so I can repay for my sins!" When all nain wants is for the people around him to stay alive.
