When their lovely childhood friend returned, they were all in a panic!

Lin Siyu realized that something must have happened between them.

However, she didn't say it outright.

We'll have to observe more closely later!

Although secretly observing a classmate's daily life seems a bit unethical.

However, I am the mental health representative, and I am doing this all for the mental health of my classmates!

Lin Siyu gave herself a legitimate reason.

"Mmm~ So sweet~"

Mu Anqi smiled and put the lollipop she had just taken out of Bai Yu's pocket into her mouth, a satisfied expression on her face.

She was shaking her head as she ate the lollipop.

Her restless little legs swung back and forth.

Combined with her adorable baby face, she looks incredibly cute.

If Mu Anqi hadn't been sitting in the last row, no one in the class would have seen her unless they turned around.

Otherwise, it would definitely cause an uproar.

Mu Anqi didn't particularly like the feeling of being the center of attention.

I think I can understand why Bai Yu wanted to sit in the back now.

Mu Anqi ate a lollipop and glanced at Bai Yu from the side.

At this moment, Bai Yu was looking at her phone.

That's about it...

Then, Bai Yu stood up and left the classroom shortly before school ended.

Watching Bai Yu's departing figure, Mu Anqi blinked her bright, watery eyes.

Where did they go again?

No, I have to go and check it out this time.

After thinking it over, Mu Anqi followed Bai Yu out of the classroom furtively.

As soon as Bai Yu stepped out of the classroom, she put on her headphones.

To get to the art building, you have to walk through most of the campus. If you go after school, there will be too many people and it will be difficult to walk.

That's why I set off a few minutes before school ends.

The teacher didn't control Bai Yu too much, as long as it didn't disrupt the class order.

Mu Anqi followed Bai Yu secretly, acting furtively.

They would find cover every now and then, and after Bai Yu had gone a short distance, they would find another cover.

Where is this guy going? He's definitely not going to the bathroom.

Mu Anqi muttered to herself as she continued to follow Bai Yu.

"Click~"

A crisp sound of a branch snapping rang out, startling Mu Anqi, who looked down at her feet.

This is bad!

Where did that branch come from? I wasn't looking and stepped on it.

Are we about to be exposed?

Mu Anqi awkwardly raised her beautiful eyes and looked at Bai Yu's back.

Bai Yu didn't turn around and continued walking on her own.

The music playing in the headphones was so loud that it completely shut out the rest of the world.

Bai Yu looked at the lyrics on her phone, glancing up at the road every now and then.

Throughout the entire process, they did not notice Mu Anqi's presence at all.

When they reached the art building, Bai Yu put away her phone.

Back in the old classroom, Bai Yu took off her headphones, carefully wrapped them up, and put them in her pocket.

A half-open window of the old classroom let in a warm breeze.

He gradually began to play a few pages of the newly borrowed guitar tablature.

"Oh?"

Bai Yu was a little surprised, looking at the guitar tabs being blown by the wind.

The breeze gradually subsided, and the pages of the guitar sheet music stopped turning.

He looked down and saw it was the sheet music for "Sunny Day".

Bai Yu has already achieved a certain level of proficiency in this song, and he can play it with ease.

Since the wind has chosen it, let's play it today.

Bai Yu smiled faintly and picked up the guitar that was placed to the side.

Sitting on the windowsill, the wind gradually blew in, ruffling the stray hairs that fell across Bai Yu's forehead.

The classic prelude to "Sunny Day" begins, tinged with melancholy as played by Bai Yu.

After the prelude, the crisp sound of the piano arrived as expected.

It seems that my friend is still here today.

Bai Yu smiled knowingly and continued playing the guitar.

After playing the verses, we've reached the chorus.

Bai Yu closed her eyes slightly, not continuing to look at the guitar tabs, because she was already very familiar with them.

Now I'm fully immersed in collaborating with the piano.

If playing an unfamiliar piece is like the piano intentionally waiting for the guitar, wanting to take its hand and walk side by side with it.

Then, playing a familiar tune, the guitarist and pianist held hands and danced a waltz in perfect harmony.

Bai Yu strummed the guitar strings, unable to resist softly singing along.

"On this windy day, I tried holding your hand, but the rain gradually intensified until I could no longer see you."

"How much longer until I can be by your side? Maybe I'll feel better when the sun comes out."

Just as Bai Yu was about to continue singing, a sweet female voice suddenly rang out.

The voice was familiar and gentle, its emotion seemingly filling the entire old classroom.

Once upon a time, there was someone who loved you for a very long time~

Bai Yu opened her eyes, and the guitar music stopped abruptly.

His eyes flickered slightly, and he looked up. It was Mu Anqi.

She stood at the back door of the old classroom and softly sang "Sunny Day".

Although the guitar stopped, the piano music continued, and the emotion in the playing intensified.

"But the wind just kept blowing us so far away~"

Mu Anqi slowly walked towards Bai Yu.

It was only then that Bai Yu realized she had been lost in thought.

He hurriedly continued strumming the guitar strings, his well-defined fingers sliding across them.

"I finally got to love you for one more day~ but in the end, it seems you still said goodbye~"

Mu Anqi sang lightly as she walked to Bai Yu's side.

The gentle breeze blowing in through the half-open window gradually ruffled Mu Anqi's hair.

She moved swiftly and jumped onto the windowsill, sitting side by side with Bai Yu.

"The day I skipped class for you..."

Mu Anqi was still singing, but her voice carried a hint of reminiscence.

She has a beautiful singing voice, something Bai Yu cannot deny.

He quietly played the guitar, and together with Mu Anqi, they completed the song "Sunny Day".

"The rainy days that have disappeared~ I wish I could experience them again~"

"I didn't expect I still had the courage I lost~ I want to ask again..."

Mu Anqi turned her head to look at Bai Yu.

He played the guitar intently, his gaze behind his glasses deep and profound.

"Will you wait or leave?"

Mu Anqi sang softly.

She looked at him, but he didn't look at her; he just focused on playing the guitar.

Finally, the entire piece "Sunny Day" came to a close with the last note of the piano.

Neither Mu Anqi nor Bai Yu spoke.

This scene evokes a sense of tranquility, reminiscent of the line, "East and west boats are silent, only the white autumn moon shines on the river."

The silence was broken first by Mu Anqi.

"Bai Yu, you can play the guitar? How come I didn't know that?"

Mu Anqi giggled and jumped off the windowsill next to Bai Yu.

She casually sat down on a desk in the old classroom and looked up at Bai Yu, who was sitting on the windowsill with a guitar in her arms.

Bai Yu lowered his eyes and remained still for three to five seconds while holding his guitar.

Finally, he let out a long sigh and put down his guitar.

"A hobby I just learned. Also, how did you find this place?"

Bai Yu slowly closed the guitar sheet music and glanced out the window.

My "friend" who plays the piano seems to be quietly waiting for the next piece.
