Living as a Butler to the Northern Duke

Lee Seonyu, an orphan who has lived alone all his life, is a perennial job seeker.
After a night of heavy drinking with a friend, he wakes up to find himself possessed by a character in a dark, explicit novel he recently read.
And the character he transmigrated into?
None other than Ed, a lowly servant who gets killed by the revenge-driven male lead!
But could it be that he transmigrated into the character too early?
In the original story, the male lead is just a 9-year-old boy with gentle eyes, mistreated as an adopted child.
Seeing the boy, Ed recognizes a reflection of his own orphaned past and decides to help him reunite with his lost brother.
“Congratulations, Young Master Ronan! And to you too, Your Grace, Grand Duke Asnel Linden!”
In the original novel, he was only briefly mentioned, but Grand Duke Asnel Linden is known for ruling the northern region, feared even by the imperial family for his cold and ruthless nature.
Yet, for some reason, he’s looking at Ed with a strange expression.
“Ed, do you have a significant other, or someone you’ve promised your future to?”
No way… could it be…?
