"What's wrong, Ryuto? Are you feeling unwell?" Anna asked, looking concerned as she noticed Ryuto's strange expression.

"No, it's nothing... Oh, by the way," Ryuto suddenly remembered something and exclaimed.

"What is it?"

"I've been meaning to ask since just now, where is the restroom?"

Anna just smiled and replied, "Oh, I see. When you leave this room, turn left and it's at the end."

"Is that so?"

"Or, should I take Ryuto there?" Anna offered to get up.

However, Ryuto stopped her with a few words, "No, I don't want to trouble you with this. I can go by myself." With that, he dashed out of the room.

He couldn't bring himself to let a girl lead him there, and besides, he was feeling a bit embarrassed to face her now.

Ryuto wanted some time alone to collect his thoughts and let everything sink in.

After Ryuto left, Anna was the only one left in the room.

At that moment,

*Ding!*

Suddenly, a ringtone sounded.

Huh? What is that sound? Anna wondered as she got up to find the source of the sound. It didn't take her long to find it because it was very close by, but...

Oh? A phone? And it's Ryuto's? He must have accidentally left it here. Anna thought as she looked at the phone on the chair.

But the ringtone kept going on and on.

What should she do? Wait for Ryuto to come back, or bring it to him? Waiting for Ryuto might cause a delay, although she could try calling back; but if it was something urgent, it would be a problem. So, should she take it to him? As much as she wanted to, she quickly dismissed the idea - Ryuto was in the restroom now, and it wouldn't be appropriate to disturb him.

Then what should she do?

The only option was to answer it herself, although it was impolite, there was no other choice.

With that in mind, Anna walked up and neatly picked up the phone from the chair.

Huh? Asuka? Who could this be? Anna wondered as she saw the caller ID on the phone.

It should be one of Ryuto's friends, he must have many friends unlike herself.

So, without any hesitation, Anna pressed the answer button.

"Hello, you must be Asuka, right? Is there anything I can help you with? Ryuto is not here at the moment," Anna said calmly.

"Oh, I am Asuka, is the idiot brother not there?" a young girl's voice came through the phone.

And from that address, could it be Ryuto's sister?

Just as Anna thought about it, someone at the other end of the phone immediately reacted, as if they had just realized something suddenly.

"What? A girl...? Who are you? Why do you have the idiot brother's phone?"

"You must be Ryuto's sister, right? Ryuto is not here right now, so I answered the phone for him. Is there anything I can help convey?" Anna replied, though the other person on the phone seemed skeptical.

"Still, Ryuto? What is your relationship with the idiot brother? Why do you casually call him by that name?"

"I am Ryuto's friend," Anna answered.

"Friend? You must be from this country then, I haven't heard that the idiot brother had any friends overseas," the person seemed unconvinced.

"It may not sound right, but Ryuto and I just met yesterday."

"Yesterday?"

For some reason, the tone of the other person's voice suddenly changed.

"That idiot brother actually... without my knowledge..."

And then she murmured something under her breath, but Anna didn't hear it because the voice was too low.
