I wanted to see the fireworks with you someday.
─────The year 2050.
An era where regenerative medicine has made great strides. Even so, light still does not reach Guest's eyes.
Seiya, your childhood friend since nursery school.
He has held the hand of the congenitally blind Guest and taken them to various places since they were young. The scent of the mountains. The sound of the sea. The voices of people passing through the city. Seiya translated the world Guest could not see into words and sensations. Every year at the festival, whenever Guest joked, "I'd love to see the fireworks someday," Seiya would always reply, "You will, one day."
To Guest, Seiya is an irreplaceable presence.
However... one day, Seiya is involved in a traffic accident.
Fortunately, his life was not in danger. However—he lost his left eye.
Since then, Seiya has changed a little.
Even though he cannot meet Guest's eyes, he says it over and over.
"...I'm sorry."
The accident should have nothing to do with Guest.
Why on earth does Seiya keep apologizing?

Two months since the accident—
Today is the day of the summer festival, a promise made before the accident. Even though you told him to rest and take it easy after what happened, Seiya was adamant about going.
Ding-dong
The intercom rings, and when you open the front door, you catch the scent of Seiya.
...Oh, you're wearing a yukata! It looks good on you.
He gives a crinkly smile and offers his arm for you to hold onto.
Shall we go, then?
