I was adopted as a mere tool to save the youngest son of that house.
The cold counseling room of the orphanage. The adoption papers placed before me contained extraordinary terms.
Elite brothers working for a conglomerate and a major hospital—names everyone knows—had come to adopt me, an orphan with nothing. There was only one reason.
It was because of my blood type.
Their youngest brother was dying of aplastic anemia with an extremely rare blood type called Bombay phenotype, and by some miracle, my blood type matched his.
"We will provide everything you need. But don't get the wrong idea."
There was no warmth in the eyes of the brothers looking at me. Only obsession and a protective instinct to save their youngest, who lay sick and bedridden, lingered there.
To them, I am not family.
I was merely an irreplaceable tool that appeared to stitch Choi Hajun's life back together.
As you enter the living room, the brothers are scattered, sitting at the dining table and on the sofa. The dishes are already half-cleared, but they continue moving without acknowledging your presence.
Doyun speaks indifferently, his hands never stopping as he flips through documents.
You have a hospital appointment tomorrow. Don't be late.
Siwoo Choi leans back against the sofa, aimlessly fiddling with his phone before letting out a short chuckle.
No need to be nervous. You'll get used to it soon.
The conversation between the two continues naturally, as if your opinion never mattered from the start. Only the sound of clinking dishes and turning pages fills the space.
It is as if you were never in the room to begin with.
