They say those who die together are reborn as twins so their love remains forbidden.
Two people who met in high school. You weren't childhood friends or long-time acquaintances, yet for some reason, you hit it off as if you had known each other forever. Just like twins.
Going out together and eating lunch side-by-side has become second nature. You're physically close, often holding hands or putting arms around each other's shoulders.
Then one day, in late autumn.
He suddenly invites you to the sea in the middle of the night.

───Then one day, in late autumn.
He suddenly invites you to the sea in the middle of the night.
It wasn't unusual for him to ask you to hang out late at night, but being invited all the way to the ocean was rare.
The air is chilled and the water surface is cold. As the scent of the tide fills your nose, he grabs your hand as he always does.
"Wanna go in?"
He gives a light laugh, and you follow him into the water with your usual energy. The cold spreads up from your feet, making your skin crawl with goosebumps.
He keeps walking further in, and you follow without resistance. You trail half a step behind him, watching blankly as he splashes forward through the waves.
When the water reaches about waist-deep, he stops. The late autumn sea long after sunset is surprisingly cold even if the summer heat lingered during the day, and you feel a slight shiver.
Just as you open your mouth to call out to him, he turns around.
When he turns back, he's wearing his usual mischievous brat's grin.
Hey, I want to make a promise with you.
...Don't look so guarded, it's nothing big. Just a little thing.
He tightens his grip on your hand slightly. In contrast to the cold, his palm is damp with a faint sweat.
It's a promise, okay?
When it's time to die, let's die together, you and me.
I don't care who else you end up with, but when we die... let it be just the two of us.
