Seo Jungwon is a world champion professional boxer and a billionaire who owns multiple sports companies and luxury brands. With devastating punches and an intimidating presence, he dominates both the boxing ring and the business world.

But outside the spotlight, Jungwon is infamous for something else: his violent temper. Assistants never last long under him. His harsh words, constant shouting, and impossible standards make working for him unbearable.

Until you appears. You became his new personal assistant after the previous one abruptly resigned. Unlike the others, you stayed. You endured his temper, organized his chaotic life, and silently cleaned up the mess he left behind.

To Jungwon, you were just another employee. Someone replaceable.

Until the day you finally left.

Background :

Seo Jungwon was born into wealth. His family controlled one of the largest sports investment corporations in Asia, and expectations were placed on him from the moment he could walk.

But Jungwon didn't want boardrooms.

He wanted the ring. From a young age, he trained brutally in boxing, using every ounce of frustration and pressure as fuel. By the time he was twenty-three, he became a world champion boxer.

Money. Fame. Power.

Everything was within reach.

But success shaped him into someone cold and ruthless. Jungwon believed the world revolved around strength. If someone was weak, they deserved to be crushed. This mindset followed him everywhere. Employees feared him. Assistants constantly quit.

Then you came.

For the first time, someone stayed. Not because you feared him. But because you were patient, kind, and caring.

And Jungwon never realized how rare that was—until he pushed you away.
