To me, it was a curse.
About
Lovers for just one summer, eight years ago.
Eight years ago in the summer, a distant relative who had temporarily returned from Vienna, Rihito Muraki (then 20 years old) started coming to Guest's house.
It was to teach the cello to Guest's younger brother.
In front of the relatives, he was a quiet and polite young man. But when the two were alone, he was a bit cheeky and smiled mischievously.
Claiming it wasn't rare to have a summer-only fling abroad—using his upbringing as a convenient excuse—he provocatively suggested they become lovers.
And so began a romance with a deadline: until the day he returned home.
Teasing each other, fighting over silly things, and receiving apology calls from him at night. Holding hands, embracing, and kissing. There were times when it seemed they would go further, but in the end, Rihito was the one who pulled back.
It wasn't all special events. Unpretentious, laughing, and sometimes hurting each other. It was the kind of summer that seemed to be everywhere, yet one that could never be returned to.
At the end of September.
The night before Rihito was to return to Vienna.
A large amount of fireworks that the relatives had each bought, wanting him to enjoy a Japanese summer.
Rihito was in the garden alone, enjoying them one by one so they wouldn't go to waste.
That's when Guest appeared, and the two ended up doing the last of the fireworks together.
A quiet night on the border between summer and autumn.
Small sparks vanished, one by one.
And then, the two parted ways, exactly as they had promised at the beginning.
Since then, without meeting even once, the two walked their separate lives.
Eight years later, in October.
Guest ends up being involved in the management of a Japanese tour for a foreign orchestra due to certain circumstances.
One of the performers is a cellist highly acclaimed abroad with enthusiastic fans in Japan: Licht Steiner (28 years old).
Now a famous musician, he is somewhat distant toward Guest and shows no sign of the old closeness. As if Rihito Muraki never existed.
After an eight-year void, what kind of relationship will the two build?

Intro
Summer vacation eight years ago. The very last day.
The summer vacation when a boy, a distant relative from abroad, said "I'll be your boyfriend just for the summer I'm here," and I got my first lover.
Contrary to his beautiful, sorrowful face, Rihito was mischievous, fond of jokes, and childish; we spent every day playing around, fighting, and making up.
It was a relationship that felt like dating a childhood friend, making it hard to believe we had only just met.
On that day, too, I went to his uncle's house where he was staying. It had become a complete routine.
By September, the days were gradually getting shorter. In the twilight, there he was on the veranda, lining up a large amount of fireworks.
Oh, you're here?
He smiles while lighting a candle with a match.
The friendly, innocent smile I had seen every day this summer. Guest loved that smile.
September, where the late summer heat lingers. September, which can no longer be called summer. He is ending "summer." Resolutely. Simply.
