1. A familiar face.

- Two, Three (BTS) 

The halls of Shin A High are filled with the sound of chatter, students in matching uniforms mulling around. The newest addition to Sky Castle, Hwang Woo-joo, is being given a tour by the Cha twins.

"And there's the observatory," Cha Ki-joon said, voice bored. His hands are shoved into his pockets, tie loose and shirt untucked from his trousers. His brother, Cha Seo-joon is the complete opposite, blazer neatly buttoned up, tie knotted up, uniform pristine.

"You guys even have an observatory here?" Woo-joo asks, surprise coloring his tone as he looks at the large room, a telescope visible even from afar, the sky visible from the glass that surrounds it. "Wow. Rich kids really do have everything,"

"There's a reason as to why the tuition fees is so high," Seo-joon replies, smiling in amusement.

"Do all of the children from Sky Castle go here?"

"Yeah. It's pretty much tradition to send us kids here, because of how the school has a pretty good reputation,"

"Have I met everyone from Sky Castle?"

"Not everyone," Woo-joo blinked, turning to face the two brothers. "You know the house that's been locked up ever since you came here? A family actually lives there, but they went away for some business,"

"Really? Who are they?"

"The Songs. One of the most prestigious families in all of Sky Castle," Woo-joo tilted his head, listening intently. "They've been living at Sky Castle ever since it was made. The earliest Song actually helped design and build Sky Castle, which is why they're adored by everyone living there now,"

"The Songs have always lived at Sky Castle, at the grandest house in the entire neighborhood. Right now, Song Sang-hoon is the head. He's a very prized engineer, having graduated from school that has a name I can't even pronounce,"

"It's that fancy," Ki-joon nodded solemnly, snickering at how Woo-joo's eyes widened.

"They're a five member family. Song Sang-hoon and his wife, Song Ara. They have three kids. The eldest is their son, Song Sang-jun. He used to study at this school too, but graduated and attends SNU medical,"

"Sang-jun hyung's really cool," Ki-joon said. "He's quiet and doesn't talk much, but he's always taking us wherever we want and making us laugh with how honest he is,"

"The youngest daughter is Song Hana. She's about Ye-bin's age, short and really bubbly. She's known to be one of the smartest kids at our school, but struggles with her Korean because she used to live abroad with their mom when she was younger,"

"That's just two kids. Who's the third one?" Seo-joon's smile widened at this, looking mischievously at his brother.

"Oh I saved the best for last. As Ki-joon usually says, she's the most important member of the family," Ki-joon turned red, shoving at Seo-joon, flustered for the first time ever.

"She?" Woo-joo echoed.

"Song Yuna," Ki-joon answered, gaze faraway and eyes lit up in a way that Woo-joo has never seen before, soft and fond.

"She's the middle child, and is the same age as us. Yuna-ah's actually in our class. She's really bright and cheerful, and generally considered a troublemaker, but everyone loves her too much to say anything,"

"She's friends with everyone. Nobody dislikes her. She's sweet and kind-"

"-and an annoyance but we adore her," Seo-joon cuts in. Ki-joon nodded in agreement. "Not only that, but she's usually in the top five of students, usually competing with Ye-seo and Hye-na. But she doesn't take studies as seriously as them,"
