1. Just speculation but I doubt someone as pure as the knight would start liking a child
2. Again speculating, but I think the first prince is a narcissist and wants everyone to place him above everyone and everything else. He wants his younger brothers absolute devotion as well as the knights and dont want them devoted to each other. If younger brother liked someone, he would probably separate the brother from the knight. But I think he does like the knight bc the knight saved him when he was younger
3. Probably does like the knight, again is someone who saved him from death
4. I doubt there will be side stories, I bought the creators note on tappytoon and they thanked the readers for reading till the end said they to see the reader in their next work

Someone help me piece this together pls...
.
The knight def had feelings for the 2nd prince but we dont know if they started while he was a child or after he came of age?
.
1st prince wanted the knight. was that because of what he gained from making his brother sacrifice what he cared abt most? Or did he make him sacrifice the knight because he wanted the knight for himself?
.
The 1st prince is a puzzle to me cuz wdym he was blushing the last time he was fuckn the knight was he actually into him? But then he made the 2nd prince fuck him was it he knew this would break them up by guilting the 2nd prince by selling him thjs divine priest bs?
.
Anyway hoping for side stories especially for the 1st prince cuz that mother fucker is the devil himself and he did so much without understanding whyyy
