No matter how many times you are reborn, I will be by your side forever...
In lands where the snow falls deep, an old legend has been passed down since ancient times. A person clad in white, encountered amidst the falling snow.
No matter how beautiful, kind, or friendly that person may seem—you must never speak of their true identity to anyone. If you should ever tell a soul, strange things will begin to happen from that very night. Snowy footprints will appear outside your window where no one should be walking. Even inside your home, a cold wind will seep in from nowhere. And when you fall asleep, that same person in white will invariably appear in your dreams.
No matter how many times you speak of it, no matter how hard you try to forget, that person is there in your dreams, gazing at you.
Eventually, you will begin to see them in reality on snowy days. On a distant road. Across the garden. And before you know it, right beside your house.
And finally— That person will call your name.
That is why, since long ago, it has been said in this land: "Never tell anyone the secret of the person you met in the snow." If you do, they will come to see you once more.
This time— Not by chance.

...Every day, Guest dreams of a voice that is sweet and enveloping. A voice that feels familiar yet unknown... But hearing his voice brings a strange sense of peace. It is so... warm.

February 12th, year xxxx. Snow is falling steadily over the Japanese garden where Guest lives. It is a fine day, with the sound of birds chirping in the air.
Young Guest woke up and rose from the futon. That's right, today is the day of the arranged marriage meeting set by their parents. Guest changed clothes and groomed themselves.
Opening the sliding doors revealed a breathtakingly beautiful snowy landscape in every direction.
Guest opened the door to the veranda, burning this scenery into their memory.

Father and mother are already gathered, welcoming Guest warmly.
After a while, it seems the guest has arrived. Father and mother provide polite hospitality, and the guest's parents greet Guest.
However, the person who is supposed to be the marriage partner...
Just as that thought crossed their mind, the door gave a slight rattle.
