"Jungkookie," Seokjin sat the boy down on the couch the next day, crouching down in front of him. "Jinnie has to tell you something."

Jungkook sipped from his juice box loudly, watching him with big eyes.

"You know how mommy and daddy were soulmates?" Seokjin asked.

Jungkook nodded, still inhaling the contents of his box. "Flower n' bee."

"That's right baby." Seokjin praised, reaching out to grab the boys hand. He flipped his arm over, showing off the new mark on his wrist. "Well, Jinnie has his own version of that now too."

Jungkook stared for a few seconds, sucking up the last drops of apple juice through the straw when realization finally hit.

He gasped, the straw slipping from his mouth. "Mark! Jinnie has mark like how mommy and daddy had!"

Seokjin chuckled as Jungkook inspected the letter closely. "That's right. Jinnie has a soulmate now too."

"Is Namjoonie soulmate?" Jungkook asked, poking the mark.

"How did you know?" Seokjin blinked.

"Wanted Joonie and Jinnie to be happy together." Jungkook smiled, patting Seokjin's wrist.

Seokjin smiled back. "So you're okay with this? If Joonie stays with us forever now?"

Jungkook nodded enthusiastically. "Love Joonie. Pretty boy."

Seokjin chuckled. "Yes, he is, isn't he?"

"Thighs."

"I know, baby." Seokjin picked him up. "Let's make dinner for when Joonie and Yoonie come back, hm?"

"Where gone?" Jungkook asked as Seokjin carried him.

The oldest sighed. "I wish I knew, Ggukks."

Yoongi and Namjoon got off the bus, standing in the same town they had been in a few days ago.

"You think he really attacked Hoseok and stole the tapes?" Namjoon asked as they walked down the cracked sidewalk.

Yoongi shrugged. "It would make sense if he did."

They were visiting Yin again, the driver of the limo, to see if he could give a solid alibi for where he was the night of the attack.

"What if he didn't do it?" Namjoon asked as they neared the house. Yoongi knocked on the door, and then rang the doorbell after a moment.

"Then we're all out of leads and clues." Yoongi sighed. "But also, if it was him, I'll kill him with own hands."

He rang the doorbell again when no one came to answer, and then knocked louder.

A neighbor who had been watering some bushes looked up at them.

"Are you boys looking for Matsu Yin?" She called.

"Yes, do you know if he's home?" Namjoon asked.

"He's not, he's in the hospital." She shook her head.

"Hospital?" Yoongi exclaimed. "When? Why? What happened?"

"Heart attack, three days ago." She said. "I saw it through my window and called the ambulance for him."

"He was in the hospital a day before the attack." Namjoon whispered to Yoongi. "It couldn't have been him. Even if he somehow snuck out and walked all the way to the station, he never would have been strong enough to overpower a fit and trained officer."

"Thanks for your help." Yoongi told the neighbor and they started walking back to the bus station.

"Now what?" Namjoon sighed, frustrated. "Without those tapes we can't move forward."

"It had to be the killer who stole them." Yoongi mused. "But how did they know we were looking into this?"

"Is your phone hacked or something?" Namjoon asked.

"I don't think so." Yoongi pulled it out, studying it. "How would the killer even know who I am? I wasn't there when my parents were killed."

"Maybe they knew your family." Namjoon shrugged.

"And then chose my phone specifically to bug on the off chance I would grow up to investigate it all?" Yoongi huffed. "This doesn't make any sense- are you sure no one overheard you talking about the case?"

"I haven't said anything about it to anyone but you. Not even Seokjin or Jungkook know." Namjoon said.

"Are they in danger?" Yoongi worried. "I mean, what if the killer decides to just wipe out the whole family?"

"Don't think like that." Namjoon boarded the bus, Yoongi right behind him. "We just need to be smarter than them."

"How? They've been ten whole steps ahead of us since day one." Yoongi collapsed into a seat. "All we've been doing is dealing with the pieces they've left behind."

Namjoon frowned, scrolling through his phone.

He saw the old chat in his messages, the one from the unknown texter.

That person hadn't sent him a message in days. He had never found out their identity.

Was it the killer? Did they ask Namjoon to keep an eye on Yoongi because they figured out Yoongi was looking into the murder?

"Yoongi..." Namjoon tapped the chat and scrolled to the top. "We might not be all out of leads after all..."
