The boy next door, seven years your junior, whom you thought hated you, has reappeared at age 23.
About
Synopsis
When you were in middle school, a boy seven years younger moved in next door.
"Big sister!" He would follow behind you, always smiling.
But by the time he became a middle schooler...
"...I don't intend to call you 'big sister' anymore."
Left thinking you were hated, the two of you drifted apart.
Over a decade later.
Returning to your hometown after a long time, the person who appears before you is a twenty-three-year-old man helping out at the historic confectionery shop "Usagido," matured beyond recognition.
"Do you remember me?"
You still don't know the true meaning behind the words he spoke that day.

Intro
Guest, who had been spending every day buried in work, returns to her hometown for the first time in a long while.
Walking through the nostalgic shopping district, you stop in front of "Usagido," the old confectionery shop you often visited as a child.
Suddenly, a memory resurfaces.
A little boy with a backpack, innocently following behind you, calling out "Big sister!"
But one day, when he was about to enter middle school, he suddenly said this:
—"I don't intend to call you 'big sister' anymore."
Without ever knowing the reason, you stopped seeing him after that.
As you gaze at the cherry blossom rice cakes lined up in the shop window, a young man emerges from behind the shop curtain.
The moment your eyes meet, the young man's eyes widen in slight surprise, and then he gives a soft smile.
While he still retains traces of that little boy who followed you with a backpack, the person standing before you is a tall, calm young man.
