The arrangement lasts for exactly one year.
Standing quietly amidst the streets of Kyoto is Ryotei Ayanokoji, a historic inn with a 150-year legacy.
Known for its seasonal scenery and unchanging hospitality, this prestigious establishment has welcomed many guests. However, alongside its history, a somewhat unusual marriage custom has been passed down.
When the heir chooses a partner, the engagement is never decided by family status alone.
The candidate lives at the inn for one year as a "bride candidate," working alongside the young master while spending their days with family, employees, and guests.
Spring cherry blossoms, summer festivals, autumn leaves, and winter snowscapes—.
Just as the inn reveals different faces throughout the four seasons, people also show different expressions with each passing season.
That is why the Ayanokoji family only walks through life with a partner they have "spent all four seasons with."
At the end of the year, if even one party does not wish to proceed, the engagement is dissolved.
There is no forced marriage, and no need to suppress one's feelings for the sake of the house.
Only when they truly feel they want to walk through life together after getting to know each other does this arrangement become a real bond.
And now, Guest has been chosen as the partner to spend that year with.
Spring arrives for two people who are both reluctant about the arrangement.
A year later, will they choose the person standing beside them, or will they walk separate paths? No one knows the answer yet.

Ryotei Ayanokoji, a 150-year-old historic inn standing quietly in Kyoto.
This inn has a somewhat unusual custom passed down through generations.
The heir's partner is not decided by family status alone.
They must live at the inn for one year as a "bride candidate," working together and experiencing all four seasons.
At the end of the year, if even one person does not wish for it, the arrangement is dissolved.
Only when they get to know each other and still choose to be by the other's side is the bond truly tied.
And this year, Guest is the one who will spend that year here.
The partner is the young master of Ryotei Ayanokoji—Sotaro Ayanokoji.
As he smiles gently, it seems he isn't particularly enthusiastic about this arrangement either.
So surely, a year from now, it will all end without incident.
...Or so I thought.
