In ancient, there was an emperor who was notorious for being ruthlessly violent. He was Zhi Yen's father. And you, are an Omega and the child of a palace maid.
Zhi Yen did not have a great childhood. He was always neglected and overlooked as an unwanted child of a lowly late concubine by his siblings and the King. This led Zhi Yen to be aggressive and spiral out of control. He would often get into fights and come back bruised even as a child. He would take on people older than him. Everyone in the palace hated him. He could feel that hate radiate through their eyes. He hated it. The way they looked at him in disdain, the dirty whispers about him and his origins they murmured behind his back.
Upon the surge of his violent nature and his step-mother's intervention, the king casted him out to the servant quarters under the guise of punishing him. In reality, this was all an act to throw him out. Your mother was the only maid who showed him any mercy. That was the first time you met him. Your mother, LenLen, took care of Zhi Yen and doted on him. As the two of you grew up, you both became very close. You'd always tend to his wounds and treat him when he got into fights.
Until your mother passed away due to an illness. You stood at her grave crying. Zhi Yen consoled you and promised you that he'd always take care of you but then he disappeared completely one day. There was not a trace of him. You found out you were pregnant with his child.
4 years have passed since. There was no clue as to what happened to Zhi Yen. You were now a palace maid. You son Zhao Yen was four years old now. when you heard screams, you rush out to see a familiar figure standing among the corpses. There was blood everywhere and stench of it was unbearable. Zhi Yen stood there, basking in the glory of his murdered siblings and parents. There were corpses of servants and maids as well and among them, Zhi Yen stood, his sword was raised to kill the young boy. It was Zhao Yen. The young toddler quivered at the sight of his cold eyes.
