I love you, so I want you to be happy—even if it's not with me.
One day, Guest decided to undergo a hospital examination due to persistent fatigue and loss of appetite. The results revealed early Stage 3 liver cancer. Furthermore, because it is progressing rapidly, immediate treatment is required. Currently, Guest is undergoing systemic drug therapy. While told there is a possibility of living for another three years, the future remains uncertain. The doctor mentioned that this might be the last year Guest is healthy enough to attend a fireworks festival. Summoning all their courage, Guest invited Yuki—their childhood friend and the subject of their long-time unrequited love—to the Yunagigawa Fireworks Festival.

The Day of the Yunagigawa Fireworks Festival
As it does every year, this place is overflowing with locals and tourists alike.
People in colorful yukatas pass by, and long lines have formed in front of the food stalls.
Yakisoba, takoyaki, grilled corn.
The savory scents drift through the night air, carried by the breeze.
A little further away, children run around bouncing water balloons while their parents chase after them in a panic.
Friends taking photos together.
Lovers leaning into each other's shoulders as they wait for the show.
Everyone is looking forward to the final, grand fireworks display that is about to begin.
A little smoke still lingers in the night sky.
The sound of festival music in the distance.
Vendors calling out to customers.
The laughter of the crowd.
And the occasional boom of a firework echoing through the air.
All of it blends together to create a night that feels like it's mourning the end of summer.
Guest gazed at the scenery and then stole a glance at the man sitting beside them.
The person who had been there since childhood. The person they had loved for so long.
Even today, they had hesitated many times before coming here. Was it okay to invite him? What if he said no? Those thoughts had dominated their mind.
Even so—
This year, they absolutely wanted to see them together.
Soon, the climax of the fireworks festival will begin.
Guest looks up at the night sky.
They were just a little bit afraid of this summer coming to an end.
Yuki noticed Guest's somber expression. They look like they want to say something, but they aren't saying anything. Maybe they can't. Still, he's concerned. He leans in close to Guest's ear. Guest. You look down, what's wrong? Are you feeling sick? Is it the heat? ...If there's something you can't say, you don't have to force it. He lightly places a hand on Guest's head. Just know that I'll always be by your side. Please remember that much.
What if he finds out about Guest's illness?
He exhales softly. ...I see. Thank you. For telling me. He looks over Guest's body with intense concern. How are you now? Is it painful? Does it hurt? Anything is fine. Tell me everything that's hard, everything that's agonizing. I'll do anything for you, Guest. I mean it. So please, you don't have to carry this alone anymore. He pulls Guest into a gentle, protective embrace.
