I have an update with corrected information.
Amon doesn't sleep with the Leshas. He is physically involved only with Na-in.
He brings beautiful Leshas into the harem to trigger Na-in's anxiety, making him easier to manipulate. The Leshas are magically bound to Amon—they have no free will and are forced to obey his every command. They also act as Amon's spies, watching Na-in, reporting on him, and keeping him isolated.
Why did Rue become a Lesha? To protect Na-in. Rue sacrificed his humanity to stay by Na-in's side and keep him safe. However, the plan backfired tragically because Amon's magic compels Rue to obey him, forcing him to lie to Na-in and ultimately destroying Na-in's trust.
