She was twenty-six. Kenji was seventy. They had known each other for only a few days.
The difference between their ages was not a minor detail that could be ignored. It affected their experiences, their physical futures, their expectations, and the practical realities of building a life together.
Yuki understood all of that.
Yet she also knew that the people who had disappointed her in the past had often been much closer to her age.
Age alone had never guaranteed maturity, honesty, or emotional safety.
Still, she did not want to mistake the relief of being treated kindly for a complete understanding of another person.
So she decided to take things slowly.
Kenji, to her surprise, seemed to share the same concern.
One evening, as they watched the sun disappear beyond the water, he turned toward her.
“Yuki, I enjoy spending time with you,” he said. “More than I expected to enjoy anything when I came here.”
She smiled.
“But I also know that our lives have been very different. I don't want you to feel that you owe me anything because I've been kind to you.”
She looked at him carefully.
“I don't.”
“Good. Because I have very little patience for emotional debts. The interest rates are terrible.”
She laughed, but he continued.
“If this becomes something more, I want you to choose it because you understand what you're choosing. Not because you're lonely, not because I'm lonely, and certainly not because I can make an excellent argument about the statistical probability of finding someone who tolerates my cooking.”
For a moment, Yuki could not think of anything to say.
She had met people who rushed to define relationships because they wanted certainty. She had met people who avoided definitions because they wanted freedom without responsibility.
Kenji was offering neither pressure nor evasion.
He was asking her to think.
That night, Yuki returned to her hotel with a strange mixture of happiness and fear.
The next morning, she made a decision that would astonish everyone who knew her.
She would marry Kenji.
Not because she believed love eliminated every difficulty, but because she wanted to explore the possibility of a life with him honestly, with her eyes open.
And, after a series of long conversations, Kenji agreed.
Ten days after they first met, they were married.
Chapter Four: Ten Days, One Wedding, and a Thousand Questions
The wedding was small.
There was no extravagant venue, no elaborate ceremony, and no enormous guest list. The celebration reflected what Yuki and Kenji wanted: something personal, quiet, and meaningful.
But outside that small circle, their decision created a storm.
When Yuki told her friends, the first reaction was disbelief. The second was concern. The third, in several cases, was suspicion.
One friend asked whether Kenji had promised to leave her a fortune.
Another wanted to know whether Yuki had considered what life would look like in ten or twenty years.
A relative suggested that she was confusing gratitude with romantic love.
Someone else went further, accusing Kenji of taking advantage of a young woman who was emotionally vulnerable.
Yuki tried to answer patiently.
She acknowledged that marrying someone after ten days was an extraordinary decision. She admitted that the age difference raised practical questions. She did not expect anyone to abandon their concerns simply because she insisted she was happy.
But she refused to accept the idea that her feelings must be dishonest because other people found them difficult to understand.
“I'm not asking you to agree with me about everything,” she told her best friend. “I'm asking you not to decide that I'm stupid before you've even met him.”
Her friend folded her arms.
“And what happens if you're wrong?”
Yuki looked down.
It was a fair question.
“What happens if any of us is wrong?” she replied. “I can't guarantee that my marriage will last forever. Nobody can. But I can make decisions carefully, keep my independence, and pay attention to how he treats me.”
Her friend did not appear satisfied.
Neither was Yuki.
There were moments when the criticism made her question herself. She sometimes wondered whether the intensity of those first ten days had made everything seem simpler than it was.
Marriage would introduce ordinary realities that beach walks and romantic conversations could not reveal. They would need to discuss money, household responsibilities, health, family expectations, privacy, and the possibility that their needs might change over time.
Affection could not substitute for those conversations.
Still, Yuki was determined to give their relationship a genuine chance.
She and Kenji began building a daily routine. They cooked together, took walks, visited bookstores, and learned to tolerate each other's habits.
Kenji discovered that Yuki liked to rearrange furniture whenever she felt restless. Yuki discovered that Kenji treated every household repair as an opportunity to invent a new theory of engineering.
Their first attempt to assemble a bookshelf ended with three missing screws and an argument about whether the instructions were written by a person or a particularly vindictive machine.
They made pancakes on Friday evenings. They watched television together, sometimes choosing shows neither of them would have admitted enjoying in public. They planted herbs in small pots on the balcony.
Their differences were real, but not always difficult.
Sometimes, Yuki introduced Kenji to music he had never heard. Sometimes, he introduced her to books that changed the way she thought about the world.
They began discussing the possibility of spending part of the year in Japan and part in Oregon, where Kenji had friends and a quieter pace of life.
For a little while, their world seemed peaceful.
Then, on the tenth day of their marriage, Yuki discovered the locked room.
And the peace she had begun to trust suddenly became something she was afraid to lose.
Chapter Five: The Locked Door
Yuki first noticed the room on a rainy morning.
The house had two floors, with a small study downstairs and several bedrooms above. Most of the rooms were open and lived-in. Books stood in uneven stacks, framed photographs lined the hallway, and a collection of old scientific instruments occupied a shelf near the window.
But at the end of the upstairs corridor stood a narrow wooden door with a brass handle.
It was always locked.
At first, Yuki thought little of it. Everyone had private belongings, and Kenji had lived alone for years before she arrived.
