:

"Wow! Your Library is huge!" She smiled as she looked around

:

"Yeah! And the secrets are even better"

:

"Where is that secret entrance"

:

"What are we trying to find"

:

"A door by the bookshelves. But it is tricky."

They began to walk around the Library as Youngchae and Yuzu began to glance

:

"Ah found it" she grinned

:

"Wow."

:

"Let's go before someone sees us" she smiled as she held onto Sana.

Perfect. Just a little more

:

"Floating bookshelves.. already."

:

"it's just like arcane."

:

I knew it

"Say, do you guys also have an underground?"

:

"Probably, if you decided to jump down again like before"

:

"Youngchae!"

:

"I was kidding"

:

"Do you want to jump down? And see what's underneath?"

:

"Can we?"

:

"Absolutely. Hold tight" she gave out a gentle smile and held onto Sana once again.

The girls landed below the Library, as they seemed to find the same underground tunnel.

:

"This.. seemed to be the same like arcane's"

:

"Y-yeah. It really does. Too bad we didnt get through the tunnel before"

:

I wonder

Sana began walking straight towards the tunnel and the sisters glanced at each other with a smirk. However the moment they pass, Sana had received a call from Jihyo

:

"Ah Jihyo."

:

"I dont think—"

:

"Hello?"

[Sana!— Sana! Where — you?!]

"Hello, Jihyo. I can't hear you"

[Get—out—yuzu—kill—]

"Jihyo? What?"

[Yuzu—she—not]

*beep*

:

"Ah.. disconnected."

:

"Ah, maybe because we are underground."

:

"I should just text her"

:

"If call wont work, your message wont be received too."

:

"I guess, Maybe we should explore when everyone is here?"

:

"We should just keep going" she smiled

:

"Are you sure? But—"

:

"It's a far drop. We'll get out after this. I really want to know whats on the other side" she grinned

:

"Okay? I guess"

Yuzu grabbed onto Sana once again, as the two sisters walked behind them, with an evil smirk placed onto their lips and eyes glowed in yellow. Yuzu's dark shadow had began to release dark figures behind her, as well as the sisters who seemed to have their own dark shadows in them.
