"That was incredible," Taemin gasped as they left the stage.

"You guys were awesome!"

Hoseok turned to see Jungkook and Yugyeom, the youngest members at the dance studio and his and his best friend's younger brothers. Yugyeom, Namjoon's youngest brother, had been dancing with them for years, but Jungkook—Hoseok's own brother—had just joined this year after Yugyeom begged him. Hoseok was glad; he hoped it would help Jungkook make friends outside his very small social circle.

"Good job, good job, well done, spectacular," Onew and Minho were going around saying, but Hoseok knew they were eager to get going—they and Kibum had an apartment outside the city limits because it was cheaper and because, after a few years, the small apartment above the studio had gotten too small for all four to live in, so now it was just Taemin's.

"Celebratory drinks?" Hoseok asked the remaining members of the group. "Joon, Yoongi, Jinyoung, and the kids are waiting."

Jaebum, who had seemed quiet all evening, sighed a little. "I can't. Youngjae and I need to get home. Mark's back tonight."

Hoseok choked on his water.

"What?" Yugyeom was staring at Jaebum, Jungkook too. Jimin, who was halfway out of his shirt, had frozen.

"Who's Mark?" Taemin asked, looking around.

Hoseok supposed, all things considered, it wasn't all that surprising that Taemin didn't know who Mark was. None of the Im brothers really talked about Mark anymore—for a few different reasons. There were no pictures of him, either, since his eighth grade graduation, when he'd still had a baby face and BamBam had pink in his hair. But Hoseok still remembered Mark from the first few years he'd known Jaebum, when Mark had always been the responsible older brother, making sure they didn't get too out of hand, being in charge when Mrs. Im was gone. He also knew Mark from conversations he'd had later, late-night conversations with Jaebum almost too frustrated to articulate what he was upset about.

"I didn't realize he was back so soon," Hoseok said carefully.

"Yeah, BamBam didn't tell us!" Yugyeom added, looking a little offended.

"We didn't really know the exact date until last night," Jaebum said, and his shoulders were sagging, eyes on the floor. "I think Bam's still figuring out how he feels about it."

Yugyeom nodded sagely and Jungkook followed suit.

"Mark's my older brother," Jaebum added, finally answering Taemin's question.

"I…didn't know you had an older brother." Taemin seemed to be reconsidering him, and Hoseok understood; Jaebum seemed like such an oldest brother, caring for BamBam and Youngjae naturally, all the time.

"He's been gone for a long time," Jaebum said, very quietly.

They got changed mostly in silence after that, but once they left the backstage, they were surrounded by people congratulating them, and Hoseok was briefly separated from the others as his parents were praising him and Jungkook, but then he saw how Youngjae's shoulders were sagging as Jaebum pulled him away from Jinyoung, who seemed surprised and confused by whatever Jaebum was telling him. Hoseok hated to see Jaebum as upset as he clearly was, but to see something getting Youngjae down actually hurt Hoseok's heart.

Trying not to analyze that too much, Hoseok made his way over, Jungkook clinging to the back of his jacket.

"You guys were so great!" Namjoon was shouting, hugging first Hoseok, then Jungkook. Then Yoongi was hugging him, feeling as strangely fragile as ever, and pulling Jungkook under one arm.

"Thanks," Hoseok muttered, eyes still on the Im brothers. "Jaebum!"

Jaebum turned, already heading out.

"Do you guys want some company?" and Hoseok's heart did a weird sort of flip when he saw the smile that slowly spread across Youngjae's face—then dropped when he saw the Jaebum's expression cloud even further.

"Better not," the older brother called back, pulling Youngjae closer and looking apologetically miserable.

Hoseok nodded, eyes lingering on Youngjae's a moment longer, and something about that made him feel a little sick. Turning, he met Yoongi's eyes instead, which only made him feel worse, because whenever Yoongi saw him staring at Youngjae, he got a look like he was in physical pain, which almost caused Hoseok physical pain. Life really just shouldn't be this complicated.
