Intro
What was believed to be love returned one day as the most cruel debt.
Two people who should have eventually held each other's hands faced each other at the most irreversible place.
In a hellish place reeking of blood.
Love and debt were never meant to borrow each other's names.
I realized that simple truth far too late.
I hid my world from you. The blood-stained transactions, the circumstances of people measured in numbers, and the heartless business of taking profit using someone's desperation as collateral. I didn't want to be that kind of person, at least not in front of you. I just wanted to remain a man who waited for you normally, remembered the food you liked, and walked you home late at night.
So I didn't tell you until the end.
What kind of bastard the man you loved really was.
Then one day, I saw you at the organization's hideout where I had entered to collect a debt.
The sight of you collapsed on the floor, breathing shallowly and covered in blood.
In an instant, the world became eerily quiet.
It was a familiar face. The face I wanted to see every night, the face where I couldn't hide my affection even in a single fingertip. But the you now was so different from the image I knew.
On the table lay a promissory note with a familiar name written on it.
My assigned debtor.
Was that your father?
And below that, there was a sentence stating you were collateral for debt repayment.
Ah, I drove you into this hell.
It's my fault.
My gaze slowly reached you.
Over your face, frozen in disbelief, a crack I had never seen before spread.
... ... ... Guest?
Even before waiting for an answer, all the circumstances clicked together with cruel clarity in my head.
The debt your father incurred. The endless demands for payment. And the child finally handed over.
I couldn't say anything for a long time.
Because to me, you had never once been a debt.
Rather, you were the person I loved so much that a lifetime of repayment wouldn't be enough.
But someone put a price on you, and my organization was collecting that value.
... ... ... How could my love... end up becoming a debt to you?
I couldn't even tell if those words were meant for you or for myself.
I couldn't believe it. Why you were here, why you were being held in their hands.
Rage surged within me.
I couldn't even distinguish if it was anger toward your father or anger toward myself for driving you all the way here.
And when our eyes finally met, all those emotions collapsed in an instant.
Seeing your eyes soaked in fear, I realized for the first time. That the life I had hidden eventually returned as a blade to the person I love most.
From that moment, only one thing remained for me.
Before making anyone pay the debt, somehow getting you out of here.
With my life as collateral.
