They wore an old-fashioned uniforms. They had an old haircut. They looked...antique.

“Jongdae hyung, it works! We’re back!” one of them said, smiled widely.

EXO K kids who were still shocked almost screamed when the first strange boys who said “hi” stopped them,

“Ya! Are you going to scream? Oh, come on! We’re just came!”

EXO K kids quickly shut their mouth and that strange boy nodded and smiled,

“Mmm, good. Like that. My name is Luhan,” he put his hand out.

“I’m Jongdae!” one of the boys continued. Waved his hand and smiled widely.

“I’m Lay,”

“Minseok,”

“Tao,” said the one who smile widely.

Finally, the last boy, who’s the tallest, said,

“I’m Kris. Their leader,” 

EXO K kids still too shocked to say anything. The leader, named Kris looked confused.

“Don’t you want to greet us, huh?”

Suho’s mouth opened widely once again while he said falteringly,

“Who...who are you?”

The boys named Luhan sighed.

“Like I said before. My name is Luhan.”

And the process happened again.

“I’m Jongdae!” the boy named Jongdae still smiled.

“I’m Lay,”

“Minseok,”

“Tao,”

“And I’m Kris, their leader,”

 Suho shook his head,

“No, I mean who’re you?”

Luhan sighed once again,

“Like I said, I’m Luhan...”

“Jongdae!” he’s still smiled.

“I’m L...” the boy named Lay started to speak but Suho stopped.

“Euarrgh...That’s not what I mean! I already know your names, but who are you? You came from where? Your clothes is strange!” he shouted, frustrate.

The strange boys say “Aaah” together and nodded.

“Aaah, you should said earlier!” boys named Lay protested.

So the strange boys sat near EXO K kids. Sehun moved a little from Minseok who sat near him while waved his hand and smiled widely. Chanyeol and D.O still so confused. Their mouth opened once again looked at Luhan and Kris who sat near them.

“Ya, don’t you want to close your mouth?” said Luhan and both of Chanyeol and D.O quickly close their mouth.

“We’re Seoul High School student, year 1998.”Kris explained.

“The boys who’s missing 15 years ago,” said Baekhyun and Kris nodded.

“You found my diary,” Jongdae pointed the diary in Suho’s hand. Suho looked at the diary.

“We found your bodies first...” Suho said and the strange boys looked sad.

“It’s sad...really sad...” Tao said while bowed his head, looked at his hands.

“We’re the victims of homicide,” Minseok added. He looked so grieve.  

“Why are you here? Why you suddenly appeared?” Kai asked.

Kris looked at his friends,

“Like Minseok said, we’re the victims of homicide, 15 years ago. Everyone didn’t know about that, they thought that we’re missing, just like you said,” 
 

“And what’s the connection with this diary?” Suho asked and Jongdae answered.

“My diary contained our soul,”

EXO K kids confused.

“Huh...what? Soul?” and Jongdae nodded.

“Because it’s my diary, it contains my memories, my feelings, my soul. I wrote everything about my friends. Because we’re being murdered, our souls trapped there,” he explained.

It’s so confusing. EXO K kids still didn’t understand.

“You found my diary. You set us free. We’re back,” Jongdae continued. “Thank you...” he smiled.

“Thank you...” Minseok and Lay added, nodded and smiled.

“Now we must find our murderer,” Kris and Luhan said.

***

EXO K kids shocked.

“Heeeh!! W...what? Mur...murderer?” Chanyeol really shocked. He stood up quickly.

“Yes,” Luhan nodded.

“Before I died, I said that I’ll find our murderer and found a reason behind our homicide. I’ve been wait for 15 years...Finally, finally I can find my murderer...” Jongdae said and his friends nodded.

“So help us,” Lay said. Tao added.

“Help us, please...”

EXO K kids surprised.

“Huh? Help what?” D.O confused.

“Please help us...Find our murderer,” Luhan explained.
