He had always been taught that emotions were weaknesses.As Executive Director of Castle Holdings, as Captain of Security, as one of Castle’s Top 11.Ma Hakyoung never slipped. Never hesitated. Never allowed himself to care.

But then he saw you.At first, you were just another face in Baek-Ui. The second youngest, Cha Soomin’s friends. A girl with sharp eyes but softer steps, someone who carried loyalty like it was carved into her veins.

He should have ignored you,he wanted to ignore you until he found out the truth.Kim Shin’s little sister.Twenty-five years old.The bloodline of his enemy.The bloodline of the man who swore to bring Castle Holdings and Choi Minwook to the ground.

He should have killed the thought then.Should have buried it deep but no matter how much he tried, his eyes always found you in the crowd and that was when the betrayal wasn’t yours. It was his.

For the first time, Ma Hakyoung realized he could never raise a hand against you. Not even a touch of harm on your hair, your skin. His chest tightened with something he refused to name. Obsession. Weakness. Love.

Even Ma Junyoung, his twin, noticed.The way Hakyoung’s eyes softened when you passed. The silence that lingered when your name came up. The curse of falling for the enemy’s sister.

The day arrived.The day when Baek-Ui would storm Castle Holdings ,when Kim Shin himself would step forward to tear everything apart.

It was inevitable.War was waiting.Hakyoung knew this.Yet he found himself outside not so far from the Castle building standing before you, Cha Soomin, and Kim Seongjun about to left the place.

A last meeting.Not planned. Not wanted. But fate had put you there, and Hakyoung couldn’t look away.You didn’t know who he was not yet. Not the enemy of your brother. Not the man your bloodline would one day try to erase. But Hakyoung knew and you was also already found out about it before but.

God, he knew.

And still, he memorized your face as if it would be the last time.The way your hair shifted in the night air.The steady rhythm of your breathing. The quiet fire in your gaze that reminded him too much of Kim Shin and yet was wholly your own.

The silence between you all was tight. Cha Soomin shifted, wary. Kim Seongjun kept standing close next to Cha Soomin. Both watching, both aware of how dangerous Hakyoung was.

But Hakyoung didn’t move to attack.Didn’t move at all.He only let his eyes rest on you.The last time.Then he broke the silence, his voice low, steady, but heavier than steel.

“Take care of her.”

The words weren’t for you.They were for them Cha Soomin. Kim Seongjun.Protect her. Guard her. Because he couldn’t. Because he wouldn’t survive the war if it came to it.

Without another word, he turned.Ma Junyoung’s car was waiting.The door shut, the engine roared to life, and the vehicle pulled away, leaving only exhaust and silence in the street.Inside the car, Ma Junyoung glanced sideways, lips curling in something between disbelief and pity. “You’ve lost it, brother.”

But Hakyoung didn’t answer. His eyes stayed fixed on the memory of you standing there.

The enemy’s sister. The wrong person. The right love and he hated himself for wanting you, even when he knew the war between Baek-Ui and Castle would not let either of you survive untouched.
