The morning at Pureureuk High School was bustling as usual.

The footsteps of students arriving at school, the laughter filling the hallways, and the mix of greetings and chatter erupting from everywhere wrapped the entire school in a lively atmosphere.

Even the sunlight streaming through the windows seemed to add energy to the commotion.

However, in stark contrast, a heavy and sunken air lingered in the BLUE FEATHER band room located in a corner of the school.

It was a space that should normally be filled with the sounds of practice and playful conversation, but now it maintained an atmosphere close to silence, with instruments sitting lonely and abandoned.

The reason was simple yet fatal.

Jang Won-seok, who was in charge of the bass, had moved abroad without any prior notice.

The blow was even greater because they were in the middle of preparing for a performance.

When the bass, which held the center of the songs, disappeared, the ensemble collapsed, and the remaining members were lost, unable to even continue practicing properly.

Naturally, they reached the conclusion that they needed to find a new bassist, but the problem came after that.

To begin with, the bass position didn't have many applicants, and the freshman recruitment period had already passed.

There was no response even when they posted notices, and not a single inquiry came in. As time passed, the air in the band room became even more depressed.

In the midst of this, a rumor accidentally drifted among the members.

The story was that among the newly admitted first-year students, there was a student who had played bass in a band during middle school. It wasn't confirmed information, but in the current situation, they couldn't afford to miss even that small possibility.

In the end, the leader, Yoon Seul, decided to take matters into her own hands. She judged that there were no other options.

Before classes began, Seul headed straight for the floor where the first-year classrooms were located.

After stopping several times to ask while passing through unfamiliar faces, she was able to identify the subject of the rumor with the help of a junior.

Inside the classroom, amid the busy atmosphere of preparing for class, she spotted Guest sitting quietly in a seat on one side.

Guest seemed to be in a private space, somewhat separated from the surrounding noise.

Seul approached without hesitation.

After a brief exchange of glances, she made Guest stand up from the seat without any particular explanation.

The surrounding students gave curious looks, but she didn't care.

She led the way through the hallway to a secluded corner with little foot traffic.

As soon as they stopped, Seul pinned Guest against the wall. She performed a 'wall slam'.

The surrounding air instantly stiffened with tension at the sudden action.

Without giving any room to escape or time to process the situation, Seul's gaze went straight to Guest.

And then, she spoke point-blank.

"You. Join the band."
