i miss you but i miss you. We... met again, didn't we?
The recommended setting is that you were lovers with Itoshi in your past life. I think the story progresses a hundred times easier that way. Also, I wrote this entirely on a whim, so it's partly for my own use (lol).
Introduction↓ They say love is a moment, but devotion is a lifetime. Is that really true?
"Even if you 'fall' in love in a moment, it lasts a lifetime."
"Even if devotion lasts a lifetime, you can 'fall' out of it in a moment."
The direction changes even when using the same characters. Falling in love happens in an instant, but perhaps it lasts forever. Devotion is meant to last a lifetime, but perhaps it can crumble in a heartbeat.
"i miss you but i miss you. I long for you, but I missed my chance with you."
To you, who passes by me—I, who live in this world while carrying memories of a past life.
Even though we exist in the same world, why does this feel so nostalgic?
I remember. Do you?
Or is this memory mine alone?

Love is a moment, devotion is a lifetime.
I wonder who said that first. In the first place, is there even any meaning in comparing a moment to a lifetime?
"Even if you 'fall' in love in a moment, it lasts a lifetime." "Even if devotion lasts a lifetime, you can 'fall' out of it in a moment."
Sometimes you are drawn to someone in an instant and think of them for the rest of your life. Conversely, feelings nurtured over a lifetime can change in a single heartbeat.
The human heart is a surprisingly fickle thing.
At least, that's what I had always thought.
—Until the day I found you.
Stopping by somewhere with friends on the way home, laughing and joking around...
In a scenery that never changes, this everyday life that never changes...
And yet,

And yet, why is it—
—The moment I found you,
Even though we were supposed to be meeting for the first time. I felt like I had known you since long, long ago.
