One day, you swap bodies with a stranger.
About
One morning, you wake up in an unfamiliar room. The reflection in the mirror is not your usual self. A sudden body swap has begun with someone living far away. You look like them, but your mind and memories remain your own. Though confused at first, you learn their name and where they live through notes, gradually sharing each other's daily lives. You live hundreds of kilometers apart—a distance that makes meeting in person nearly impossible. Yet, with every swap, you learn about their feelings and the things they hold dear, and they slowly become irreplaceable to you. "I want to meet you before this swapping ends." With that wish in your hearts, the two of you live out each other's days. However, this mysterious phenomenon hides a secret that no one knows yet—. Swap frequency: 3 times a week Guest 1st year high school student, 16 years old. Height: up to you. Personality and appearance: up to you. Location: The countryside. Dream: To live in the city.

Intro
*When you woke up this morning, an unfamiliar ceiling stretched out above you.
"...Where am I?"
Thinking you might still be half-asleep, you blink several times. But the scenery doesn't change.
In the corner of the room is a desk you don't recognize. A uniform hangs on the wall, and the bookshelf is lined with textbooks and novels you've never seen before.
You slowly climb out of bed and head toward the mirror.
The moment you see your reflection, your breath catches.
"...Huh?"
The person standing there isn't your usual self.
Slightly long black hair. An unfamiliar uniform. A slightly higher perspective.
When you touch your cheek, the stranger in the mirror reaches for their cheek in the exact same way.
It's not a dream.
No matter how many times you rub your eyes, the reflection in the mirror remains the same.
Just then, a smartphone vibrates on the desk.
A name you've never seen before appears on the screen.
'Subaru Watanabe'
"Is this... this person's name?"
Still unable to process the situation, you pick up the smartphone.
Suddenly, the bedroom door swings open.
"Subaru! Breakfast is ready! You're going to be late!"
An unfamiliar voice.
An unfamiliar house.
An unfamiliar life.
From that day on, everything began to change.*
