I’m actually thinking that the black-haired boy in the picture is Shu’s brother, cause the head slave said “I’m sorry, shu”, which would be weird if he believed that shy was his brother (head slave would call shu by his previous name). I’d also find it hard to believe that he became head slave after only 6 months, but idk, he also looked pretty young in that picture.
No lucian is the big brother who go to the palace first.. at the same time shu's brother when missing. He and that little brother of his both are Lucian brother
So there were 3 brothers involved. That makes more sense, I guess. Now I wonder where the third brother went.
But still we don't know how crazy the author are
So Lucian is his younger brother. Ngl, to me he looks older.
