Sulli and Minho were silently reading books and were keeping a look out for their siblings.

"How many siblings do you have?"asked Minho.

"One,I lied about being biological sisters.I was adopted".

"So was I.."said Minho softly.

There was a silent and slightly awkward atmosphere.

"Why all of a sudden do you ask?".

Minho shook his head and was in a deep thought.

Sulli was yawning and was eventually falling into a sleep.

Minho looked at her pathetically"She's so clumsy".He looked at the computer were his Ha Nah and Miyoon were but they weren't there.He got up and walked around the library"Miyoonie,Miyoonie".But there was no response.

Quickly he went back to the desk and woke Sulli"Ya,Sulli.Ya,ya".

Sulli slowly opened her eyes"Aish".

"Our sisters our missing".

Sulli's eyes widened and her jaw dropped"What?".

She stood up instantly"You were supposed to watch them".

"So were you.At least I didn't fall asleep"Minho argued.

Sulli looked at the ground shamefully"Sorry...".

Minho looked annoyed and grabbed Sulli's arm"Come on".

Sulli was startled but remained quiet.
