Absolutely not! No way in hell. Nathan was born a slave servant in the Southern Palace after his parents were captured as prisoners of war. He was saved by Kishiar, which is why Nathan is extremely loyal to him. Nathan was suspicious of Yuder because he was hiding his true potential and seemed to know too much. Naturally, he would be wary of him. It like when your best friend starts dating someone you've never met, and you feel cautious about them bc you want them to be happy forever.
However, Nathan's suspicion began to lessen when he saw Yuder consistently serve the Cavalry and protect Kishiar. Gradually, Nathan lowered his guard around Yuder and began to trust him. When Kishiar and Yuder eventually got together, Nathan was supportive and understanding.

Is there a chance that Nathan has feelings for Kishiar? He seems keen on making sure Kishiar doesn’t develop feelings for Yuder.
