"Ugh…We've all had a tiring day full of chores… I think everyone's all wiped out…and I'm glad that "full chore day" only happens once a year", Shuuji groaned.

Ai chuckled. "Except me!"

"Moving on… Let's go and settle down so we can get to bed," Reina sighed.

Everyone just nodded.

At their bedroom…

(Oh yes I planned for their bedrooms to be a long corridor and there are the doors to the rooms along the wall and you can make contact with the room in front and behind of you by pushing up an indoor window. There are 4 people in each room.)

Hiroto yawned. "Is everyone ready?"

"Yeah…" Everyone except Ai mumbled.

"I'M READY!", Ai shrieked.

Everyone sweatdropped when they saw her shrieking so loudly, and felt annoyed at the same time, since she had skipped her chores.

"Kay'…" Hiroto turned the lights off.

Just as Hiroto turned the lights off, Satoshi heard a strange sound.

Shfft…

"What on earth…" Satoshi groaned.

Keevelifted an eyebrow in the dark. "What now?"

Satoshi pointed towards the roof. "That tapping sound!"

"Come to think of it, I heard one too," Yuki remarked.

"Guys?" Satoshi said.

Everyone else gave him no reply.

Satoshi tried once more. "Hey…guys?"

Everyone else still gave no reply."I know we're all exhausted, but let's go and investigate", Shuuji told everyone. "There is a chance that it might be dangerous if we don't find out what's going on."

"This isn't a joke," Suzuno broke in before anyone started to complain. "We're trying to investigate so that things don't happen to us in the middle of the night, and we're basically trying to ensure our safety." Suzuno finished his sentence wearily.

"He's right, this is why I even suggested this even though we're all so tired." Shuuji mumbled.

"Fine." Reina sighed.

Everyone else just sighed, but agreed to come along.

In the main hallway near the entrance…

"Luckily I brought my torch. Its creepy and hard to see…" Satoshi commented.

"Let's listen out then track where the sound is coming from." Hiroto said.

"Yeah," Satoshi agreed with Hiroto.

Shfft…

Please review guys! What did you all think? This was fun. xD What do you guys think the sound is coming from and why it is there, and most importantly, who caused it? I'd like to hear opinions!
