I Became a Slave to the Man I Abandoned

“A s*ave like you shouldn’t call my name. Address me properly.”
“Ma, master..”
…
Nox Renerio cruelly abandoned the boy who had deeply loved him.
The boy grew up, harboring hatred and a twisted sense of twisted desire towards Nox. A desire to possess, to claim, to overpower.
As time passed and the boy became an adult, Khalid Via was at the side of the Second Prince. With the Second Prince’s orders he victoriously claims the head of the Crown Prince.
In return, the now-Emperor agrees to grant one wish.
“Your Majesty, please give me him.”
…
Nox, who was falsely accused of treason and on the verge of death, is forced to become the s*ave of the man he had abandoned long ago.
“This is what you are going to do starting today.”
Khalid straightened his body and untied his robe.
The young boy had grown up and was now lusting after him, a s*ave. Unknowingly, he tried to back away, pulling on the sheet under him. However, Khalid’s firm hand pressed down on his shoulder. Nox stuttered.
“No, this isn’t, this isn’t right…”
“What’s not right?” He whispered lowly.
“This is your sole purpose now.”
