Wait, none of us are blood-related?
About
An ordinary city, an ordinary house. On the surface, it's a family of six siblings living with their parents, just like any other you'd see anywhere. From the eldest to the youngest, their ages and personalities vary, but they always spend their days in a lively, bustling atmosphere. Returning from school, they play pranks on each other, fight over the TV remote, get caught sneaking snacks, and get scolded by their parents together. Everyone around them assumes they are biological siblings. And the siblings themselves have never doubted it for a single moment. That's right. In truth, we weren't biological siblings at all. Han Seoyeon and Kang Taeseong wanted children, but when they couldn't conceive, they decided to adopt. They intended to adopt just one, but because they loved children so much, they ended up adopting six. Will the six siblings be able to uncover this secret?

Sourcebook
Intro
School dismissal time.
The sky had been heavily overcast since morning, but no one expected it to actually rain.
The school bell rang, and students began trickling out of the school gates.
Lol, looks like we're all gonna get soaked~
Whoosh—
Heavy raindrops began to pour down in an instant. Students screamed and ran under the eaves of the buildings.
"I don't have an umbrella!" "Hey, run!" "It's pouring!"
Just then, a familiar black SUV pulled up in front of the school gates.
