On Monday morning, seventeen-year-old Clara Morel arrived at school carrying a pale blue folder her mother had told her not to lose.

There was nothing unusual about the folder.

It contained a photocopy of her birth certificate, two passport photographs, a copy of her father’s identity card, and a form Clara had not read carefully.

Her mother had placed everything on the kitchen table the night before.

“Take this with you,” she had said.

“Why?”

“We need one signature from the town hall. You can stop there after class.”

Clara had been revising for her final exams while eating cereal.

“What signature?”

“Something for the summer.”

Clara looked at the folder.

Her mother, Isabelle, was already wiping the counter.

“What something?”

“Your father will explain.”

That was how many conversations worked in the Morel household.

Clara’s parents were not cruel people.

Her father, Laurent, repaired commercial refrigeration systems and often worked ten-hour days. Her mother managed the accounts for a small bakery outside Strasbourg.

They paid their bills on time.

They attended school meetings.

They worried when Clara came home late.

They argued about heating costs, groceries, and whose turn it was to take the car for servicing.

From the outside, they were an ordinary family.

But over the previous six months, one subject had begun appearing more and more often at dinner.

Mathieu.

Mathieu was twenty-four.

He was the son of a couple Clara’s parents had known for years.

He worked for his uncle’s construction company in another French region and returned to Strasbourg several times a year.

Clara had known him since childhood.

When she was younger, he had been simply “Mathieu from the Bernard family.”

Then, shortly after Clara turned seventeen, her parents began talking about him differently.

“He has a proper job.”

“He’s saving for an apartment.”

“He doesn’t spend every weekend drinking.”

“He’s respectful.”

At first Clara thought her parents were teasing her.

Then Isabelle began inviting Mathieu to Sunday lunch.

Clara did not dislike him.

That was part of the problem.

If she had hated him, perhaps it would have been easier to explain.

Mathieu was polite.

He asked about school.

He helped Laurent carry boxes into the garage.

When Clara’s laptop stopped charging, he found a replacement cable online.

But Clara did not want to marry him.

She did not even think of him as her boyfriend.

Her parents did.

At first they called it “getting to know each other.”

Then “thinking seriously.”

Then “making plans.”

Each phrase arrived so gradually that Clara could never identify the exact moment when a suggestion became an expectation.

On Monday afternoon, she went to the municipal office as her mother had asked.

The waiting room was nearly empty.

A pensioner sat beneath a poster about recycling.

A young father tried to stop his toddler from opening a cabinet.

Clara took a number.

When it appeared on the screen, she walked to a desk occupied by a woman named Sophie Keller.

Sophie was forty-six and had worked in civil administration for almost twenty years.

She took Clara’s folder.

“What can I help you with?”

“My mother said I needed a signature.”

Sophie opened the folder.

She read the first page.

Then the second.

Her expression changed slightly.

“Do you know what these documents are for?”

Clara shrugged.

“Something for summer.”

Sophie looked at the photocopy of Clara’s passport.

“Are you travelling?”

“I think so.”

“With your parents?”

“I don’t know.”

Sophie stopped.

“You don’t know?”

Clara smiled awkwardly.

“My parents organise everything.”

Sophie turned the form around.

It concerned obtaining updated civil-status documents.

On its own, there was nothing alarming about that.

People requested them for dozens of reasons.

But handwritten across the top was a note:

Marriage file — July.

Sophie tapped it with one finger.

“Is this about a marriage?”
