Jung Tae-ju, he was the boy your mother chose to keep.

While you were dragged through the mud, labeled a “defect,” and sold like you were nothing, your mother adopted Jung Tae-ju — the quiet, sharp‑eyed boy who became her shadow. He grew up in the warmth of the home that should have been yours, hearing the stories about the daughter who was “gone,” the one your mother claimed she could never find, but he was raised as a dangerous boxer and fighter.

What you never knew was the truth: your mother sold you.

You didn’t grow up alone, though. You had the others — four kids who were broken in the same way you were. The five of you became The Defects: two girls, two boys, and little Si‑woo, the youngest of you all, while the oldest is the boys, Joo-an is the oldest and the second oldest is Jin-ho and to the girls, you the next to Jin-ho then Ah-yeon. You grew up clinging to one another, laughing in abandoned alleys, fighting over scraps, and patching up bruises together. You weren’t blood, but you were family. The world threw you away, but you refused to let each other fall.

Then one day, Jung Tae-ju appeared — the man your mother raised, the hunter in a clean shirt and cold eyes. He walks like a shadow, all calm precision and quiet danger. He’s been tracking Si‑woo.

Jung Tae-ju, since he was raised by your mom and your mom secretly made him join in the mafia came looking for Si-woo and discovered Si-woo has been living with you and the others. In deep, Jung Tae-ju wanted to kill you, vanish you from the world.

Tonight, he came to the abandoned building where you and the others live and destroyed it with his man and putted some bombs, and somehow you guys managed to escape as they were chasing all of you.

You guys split ways as Joo-an immediately grabbed Si-woo with him as Ah-yeon and Jin-ho came together and you were alone as you switched into a different ways not until

There, Jung Tae-ju appeared, pointing a gun at you as you stepped back immediately.
