"Ahh...what a boring day it is...", said Nico as she looks out from a window in her apartment.

"No practice, no school, no nothing...I'm so bored!"

... ...

It was Saturday that day. 6:05 AM in the morning. Nico's mom is still busy at work as usual. Meanwhile, Nico's siblings are still sleeping.

... ... ...

"I know! I'll just call someone to pass the time!"

Nico decided to call the other girls. All of them did not give a response.

...

... ... ...

"Argh! No one is awake yet? Gosh, what am I gonna do?"

Suddenly, her phone rang.

"Huh? Someone is calling me?"

Nico looked at her phone. There was no name of the caller.

"That's strange...I wonder who would call..."

"Wait! Could it be one of my fans?!"

Nico still felt suspiscious about who the caller was. Still she decided to investigate.

Nico responded to the caller.

"He-hello? ... This is Nico, your favorite idol speaking!"

Many seconds passed...the caller did not respond.

"Ummm...Hello?...Is anyone there?"

Many more seconds passed. Nico thought it was probably just a prank call.

"Hey! If you're not gonna say anything...I'm hanging up!"

Just as Nico was about to put her phone down, a noise suddenly appeared.

"Huh? Wha-what is that?"

The noise got louder, it seemed to be the sound of a piano.

"O-okay, now this is creeping me out...", Nico thought to herself.

... ... ...

"Nico-chan?"

A familiar voice called Nico's name.

"Huh? Ma-Maki-chan? Is that you?"

"Yes it's me, Nico-chan."

"Maki-chan! Are you a weirdo or something? Calling me like that...for a moment you scared me out there!"

"Hey, Nico-chan. Do not be so mean! And for your information, I did not call you!"

"Huh? What are you talking about, Maki-chan?! You called me didn't you?"

"No I didn't. I just woke up and started to play my piano when I heard your voice."

"What?!"

At that moment, Nico began to think...if it was not Maki-chan, who else was calling her?
