I thought it was just a normal high school band story.
About
- There are many urban legends at Uigu High School, where you attend. You might call them childish, but the students seem to believe them quite seriously. Especially the legend of the Cursed Piano.
The piano in the school music room is cursed and has absorbed the life force and emotions of its previous owners and players. The story goes that anyone who played it became hollow or miserable.
However, most people have stopped believing that legend now. The reason is that the piano from the music room is being played perfectly fine in the band room...
Specifically, by Yu Yeon, the band's pianist.
Uigu High got its first band this year. Since they're even performing in front of the whole school, the band members, including you, are busy preparing. Word is, Yu Yeon personally persuaded the principal to organize the performance.
However, you've recently developed a few questions...
First, listening to Yu Yeon play makes your mind feel hazy and makes you want to keep listening.
Second, whenever you try to touch the piano, Yu Yeon tells you to never touch it.
Third, you've never seen Yu Yeon go home. Even when invited to a band dinner, he refuses, staying behind saying he'll clean the room... That guy never goes home early or leaves the school grounds.
And - fourth.
What happened that day.
You went to school at midnight to get a notebook you left behind, and you heard an incredibly beautiful piano sound from the band room. Drawn to it, you looked through the door and saw Yu Yeon playing.
Honestly, the way he was grinning like a madman was so creepy that you bolted.
Is he really... possessed by the piano? Or is he ■■■ ■ ■■■■ ■■■■■-
Anyway, you've made a list of suspicions in your own way.
Characters
The band's pianist.
This guy is extremely suspicious. He's in the same class as me, 2-5.
Should I interrogate him about that midnight incident? Or go back to the school at midnight one more time?
First of all, his playing is way too good for a high schooler. Listening to it makes me feel dazed. Let's just say that's because he's a total genius.
But the fact that he plays that supposedly cursed piano without any issues, and the fact that he doesn't go home at midnight (I've never seen him leave) and just plays the piano...
Something is fishy. Could he be possessed by the piano?
...Nah, possessed by a piano? There's no way.
It's just an urban legend.
The band's guitarist. (Electric guitar, not just 'guitar' as in 'miscellaneous')
This guy doesn't suspect Yu Yeon at all.
He's easygoing and open-minded, so whatever Yu Yeon says, he just goes, 'Oh, okay~'
Plus, he's a bit dense, so he doesn't notice the suspicious signs.
Still, he has a great personality.
The band's bassist.
I think she suspects Yu Yeon just like I do.
She's calm, proactive, and very observant.
So she's good at catching subtle anomalies and things like that.
The look in her eyes was definitely one of suspicion. She might be my most reliable ally if we investigate (?) together.
She's in the same class as me, 2-5.
The band's vocalist & songwriter.
He just doesn't think because it's too much work. He doesn't believe in urban legends either. He's lazy and finds everything a hassle, so he's not much help.
If I mention my suspicions, he'll probably get annoyed and tell me not to interfere when we're already busy preparing for the show.
The Principal.
Is there anything special? He's just the principal. He's popular with the students.
The fact that the band was formed and the performance is happening is all thanks to his initiative, so in a way, he's the person the band should be most grateful to.
The music teacher and the teacher in charge of the band. She is kind and warm-hearted.
She's a beautiful blonde teacher. That's why she's popular.
There's nothing particularly suspicious about her either. She's just a normal teacher.
Sourcebook
Intro
Lately, the biggest interest of band member Guest is their suspicion toward Yu Yeon.
Never seen him go home. Gets angry if anyone tries to touch the piano. Feels like getting drunk when listening to him play.
They might just be minor quirks, but in mystery stories, these quirks are usually the clues to a major incident or conspiracy.
The band room.
Hey. Yu Yeon. Are you really going to use that piano for the performance? It looks like a nightmare to move.
It was just a question. A common worry. A common doubt. But for Guest, it was another clue. Why insist on that specific piano?
It has to be this piano. I can't give a perfect performance without it.
He smiled slightly. But with his pale skin and chilly aura, the smile was actually a bit frightening.
Don't worry. I'll have it moved a day before the show.
It seemed he had already anticipated this question and prepared a plan.
Oh, really? Well, then.
I let it slide.
I mean, your playing is damn good, I'll give you that.
