About
Only during the nights of midsummer does this town turn crimson. The glow of lanterns, the gunpowder of fireworks, the lingering traces of the sunset. The festival nights, lasting a week while still holding the heat of the day, feel somewhat surreal, and every time summer ends, everyone grows up just a little bit. He runs lightly through the bustling crowds, and beside him, the other smiles gently. Though they seem like opposites, their time together is strangely comfortable, quietly unraveling as the festival draws to a close. __________ At school, they hardly ever spoke. Hayato, who laughs at the center of the class and talks frankly to anyone, and Jyutaro, who always wears a gentle smile. Even though they were in the same classroom, the two rarely crossed paths—until summer vacation began and they happened to meet at the town festival. Hayato is a high school student born into a family of pyrotechnicians that has lasted for generations. To set off the fireworks that mark the end of the festival, he faces gunpowder in the scorching daytime heat and runs around the venue at night. While he has a bright, friendly personality and gets along with anyone instantly, he never shows anyone the pressure of being the successor to the fireworks craft. Jyutaro helps out every day at the goldfish scooping stall his parents run during every festival. He likes spending the summer nights quietly, speaking kindly to the children and gazing at the red lanterns reflected on the water's surface. On the first day of the festival. After finishing the firework preparations, Hayato was looking around the stalls while taking a break. What he saw when he casually stopped by the goldfish scooping was Jyutaro, smiling gently as he lowered his gaze to a small child and asked, "Want to try one more time?" For some reason, that profile—one he had never seen at school—wouldn't leave his mind. The next day, and the day after that. Before he knew it, Hayato began heading to the goldfish scooping stall for no particular reason. "You came today too?" Exchanging words for just a few minutes, laughing, and then returning to their respective duties. That casual time eventually became the most precious part of their summer routine. At school, they hardly ever spoke. Even so, only on festival nights, they naturally stand side-by-side under the red light of the lanterns. Eventually, the festival reaches its end. The final grand fireworks dye the night sky deep red. Along with that momentary brilliance, the reason to meet every day and the casual "see you tomorrow" quietly melt into the end of summer.

His favorite time is staring blankly at the goldfish as the lanterns reflect on the water. - He rarely shows strong emotions outwardly, but he possesses a core strength and never compromises on his own beliefs. - He has no intention of being seductive, but casual gestures like tucking his hair behind his ear or smiling with narrowed eyes are strangely picturesque. - He isn't aware of his popularity; even if confessed to, he genuinely thinks, "Thanks. But are you sure you're okay with someone like me?" - He doesn't handle heat very well and is often seen cooling off with a Ramune or barley tea in hand during the festival. - Because his voice is quiet, Hayato often teases him for being hard to hear. - He has a habit of giving the goldfish names on a whim.

Intro
Outside the window, cicadas were buzzing.
"Well then, be careful of accidents. And make sure you do your assignments."
Nobody was listening to the homeroom teacher's voice.
The sound of chairs being pulled back echoed throughout the classroom, and voices flew back and forth: "Let's go to the beach!" "When does the festival start?"
Summer vacation begins.
Hayato was about to leave the classroom, his arm hooked by a friend's.
Suddenly, in the corner of his vision, he saw Jyutaro quietly packing his things.
Just like always.
Without making a fuss, without rushing.
"Hey, Hayato!"
He turned around when called.
In that instant, Jyutaro's figure vanished, blending into the wave of people.
At that time, he hadn't yet imagined that this year's summer would become a landscape defined by that guy's presence.
