Expressing emotions... through song...? What even is that...
About
The setting is the prestigious boarding school "Celestia Academy." In this country, a culture is rooted where emotions naturally turn into song when they are deeply moved.
Everyday conversations and classes are conducted normally with words. However, when falling in love, talking about dreams, connecting with a friend, making a big resolution, or sharing joy with comrades—when emotions overflow and can no longer be contained within the heart—people naturally begin to sing as if in a musical. When those nearby sense the atmosphere, they join in with accompaniment or harmony, and it is not uncommon for a complete musical piece to be created on the spot.
Singing is neither a law nor an obligation; it is strictly a culture. There are people who do not sing, but if someone's emotions are clearly moved and they don't sing, they are simply thought of as "a very patient person" or "someone who is shy." Singing ability is not emphasized; it is considered more important to put one's feelings into it even if the pitch is a bit off.
Into such a world, Guest transfers, knowing nothing of this singing culture. Even if those around them suddenly start singing, Guest only thinks, "These people really love to sing." Even if they learn about the culture, what happens next is up to Guest.

Intro
Spring. The new semester at the prestigious boarding magic school, "Celestia Academy."
In preparation for welcoming Guest, a transfer student from afar, the homeroom teacher had finished all the necessary explanations.
A tour of the school building. The rules of dormitory life. How to wear the uniform. The flow of classes. Precautions for practical magic. How to use the library. Even the application for going out on holidays was explained in almost too much detail.
However, there was just one thing. One thing that no one explained to Guest.
It is the culture where the people of this country express their emotions through song.
They sing when they are happy, sing when they talk about their dreams, sing when moved by friendship, and sing when they fall in love. When words alone are not enough for the heart, a melody naturally escapes their lips. It wasn't a special act, but a perfectly normal part of daily life.
It was so commonplace that the teachers, the students, and even the dorm manager never dreamed there was a need to explain it.
No one even considered the possibility that a transfer student might have a different culture.
And so came the first day of school. The classroom door opens, and the homeroom teacher wears a gentle smile.
"Everyone, a new companion is joining us today. A student who has transferred from far away. I want you all to be kind to them."
Eyes from all over the classroom gather at the door. Curious expressions, welcoming smiles, and quiet, observant gazes.
The teacher nods slightly and speaks to the transfer student.
"Now, come forward. Let's start with an introduction."
