The old man's hand slipped from the door panel.

The mood in my heart is really not good.

…

The old man lowered his head.

Silently suppressing the irritability that almost made me want to get angry.

…

Too late...

The old man knows.

…

The old man sighed.

Just wait until night to come again.

The old man was a little unwilling.

Although he was not sure whether there was the answer he wanted on this floor, but because of the frustration...

All three houses were actually empty.

He became more and more eager to meet the owners of these three families.

I want to ask them the question he has been asking: Have you heard the sound of pipa at home recently?

…

The old man was lost in thought for a while.

When I suddenly came back to my senses, I felt a little confused for a moment as if I didn't know what day it was.

The old man shook his head vigorously.

He reached out and pressed his temple again.

…

The old man's eyes regained clarity.

The old man finally took a step forward.

…

The old man returned home.

Just as he inserted the key into the keyhole and before it turned, the door opened.

…

The old lady looked at the dazed old man in front of her with slightly raised eyebrows.

"I'm finally back."

"Why have you been gone so long?"

…

"you……"

The old man was a little surprised.

"You want to go out?"

…

"not now."

The old lady shook her head.

She is indeed going out today.

But it's afternoon.

"I came to open the door for you because I heard your voice."

"I just called you."

There was a bit of disapproval on the old lady's face.

"Then I found your phone on the bedside table in the room."

She was really angry at that moment.

"Next time you go out, remember to take your phone with you."

"It makes people anxious that we can't contact so many people."

…

"I'll be upstairs or downstairs."

The old man was a little embarrassed.

If he really has to go out, he will definitely remember to bring his mobile phone with him.

…

The old lady rolled her eyes slightly.

"I don't care whether you are upstairs or downstairs..."

"Whenever you leave this house, take your phone with you."

"Did you hear me?"

…

"knew."

The old man nodded.

He knew that the old woman was worried about him.

Every time the old lady goes out, he reminds her not to forget her mobile phone.

…

"so……"

The old woman stepped aside to signal the old man to come in, and asked casually, "Have you found the person who plays the pipa?"

…

The old man paused slightly while changing his slippers.

Then the old man walked into the house on his slippers.

"……No."

…

"No?"

The old woman was surprised.

"None of them?"

…

"Um……"

The old man shook his head.

"I only asked three households on the first floor below."

"None of them have heard the sound of the pipa."

"There is a family whose children are learning piano."

"All the neighbors heard was the sound of the piano."

…

"As for the floor upstairs..."

The old man still felt a little regretful when he said it.

"I was late."

"No one is home anymore."

"...I have to wait until evening to see it."

…

"Are you going there tonight?"

The old lady felt a little strange in her heart.
