I need help finiding this bl manwha All I remember is this dude ends up in this novel as a side character that dies from the Duke bc he found out he was writing letters for someone who was courting the duke and he already didn't like the Duke bc he called his books trash ruining his writing career and so he stops writing letters for people and goes out to look for a job he ends up at the dukes manor working as a gardener. He has brown hair with glass and the Duke can change his appearance his hair is originally blond but he can change it to black and wears a mask to be mysterious. It recently finished the first season.
