"The piano is over here," Chinami Sawaguchi walked onto the big stage of the concert hall and looked at the piano in the corner. "It was tuned when it was delivered two days ago. Do you think it needs to be re-tuned?"

Chi Feichi put his right hand on the keys, moved his fingers up and down, and played a crisp and simple melody. He said to Sawaguchi Chinami, "That's it."

The concert hall that has not yet opened is a bit dark, and no matter how exquisite and elegant the stage decoration is, it will inevitably make people feel lonely. However, Chi Feichi stood in front of the piano in a formal tuxedo, as if to tell everyone that even if he is standing alone on the stage, he will still feel lonely.

Even if there is no audience, he can still play seriously.

The previous feeling of loneliness was inexplicably diluted, and there was a solemn atmosphere that made people unable to help but take it seriously.

Hui Yuan Ai looked at Chi Feichi's hand.

She used to think that those hands with clear joints were born to hold scalpels, but now they feel like they were born to handle the black and white keys of the piano.

The three children didn't have so many sensitive thoughts. They only paid attention to the smooth and light movements of Chi Feichi's fingers just now, and their eyes were bright.

"So...so handsome!" Mitsuhiko exclaimed.

Yuantai looked confused, "I want to study piano again in the future."

"Yuta..."

Ayumi sweated and smiled dryly, "If you like it, you can learn it now."

Chi Feichi sat down on the piano bench, "I haven't played the piano for about nine years. Let me get used to it first. I can teach you some simple songs later."

"Nine years..." Mitsuhiko thought for a while, "Did Brother Chi learn piano when he was eleven? No, the age when he started learning should be a little earlier."

"Five years old."

Chi Feichi said something and started playing the music.

Amidst the crisp and cheerful piano music, the three children were stunned for a moment, trying to remember something, then they soon started laughing and started singing along with the next piece of piano music.

“Jingle bells jingle bells…”

“Jingle all the way…”

"Oh what fun it is to ride..."

After singing for a while, Ayumi turned around and asked curiously, "Haiyuan, why don't you sing?"

"I..." Haiyuan Ai's mouth twitched slightly, trying to keep his expression calm, "I won't..."

"Jingle bells", jingle bells.

Sure enough, with three children here, she shouldn't expect to hear piano music such as Adelina by the Water, Nocturne, and Destiny...

"Haiyuan, didn't your previous school teach you?" Yuantai asked.

"This song is very simple," Mitsuhiko said positively, "If you don't know, you can hum it slowly first..."

"It's fun if we all sing together," Ayumi said with a smile, "Haiyuan, why don't you come too!"

Chi Feichi paused for a moment and started playing again.

"Follow me!" Ayumi said to Haiyuan Ai, looking serious as she waited for the singing to begin.

“Dashing through the snow…”

"In a one horse open sleigh..."

Haihara Ai was forced to join the "Jingle Bells" chorus, and countless thoughts flashed through her mind.

Why would she do such a childish thing together? She really wanted to commit suicide every minute...

but……

Chi Feichi, someone older than her, is also doing it, so just treat it as accompanying a child...

After singing it once, the three children were still interested and continued to sing Jingle Bells by name.

The reason is...

"Haiyuan doesn't know this song, so how can he do it?"

"We must teach her today!"

"That's right, our young detective team should be unified!"

Haibara Ai:"……"
