Years later, Serena still walks the same route home.

Still works at the same hospital.

And when she finds time, she reads Kei's final letter — the one he left behind, folded carefully and worn from her fingers returning to it again and again.

My beloved Serena,

There are no words to express how much love and joy you brought to my life.

You didn't just treat me as a patient. You saw me — really saw me — and believed in me when I couldn't believe in myself.

Thank you for helping me realize... that life is not always about transformation. It's not just about changing what's outside, or proving something to the world.

You taught me that even in the body I once hated, I was already worth loving.

That there will always be someone out there who will see you as you are, no matter what you look like.

For me, that someone... was you.

My only regret is that I will be going to a place without you.

I would have given anything for one more coffee date, one more slow dance in the living room, one more sunset on the beach. But if I had to choose between forever without you or a few precious months with you...

I would still choose this.

Every time.

And if there is indeed another life after this one...

I promise that I will find you again.

No matter how long it takes. No matter what I become.

I will always remember.

And I will always see you as Serena —

My love...

My life...

My everything.

Love,
Kei

And sometimes, in the quiet of her nights, she looks at an old photo tucked inside a worn journal—the one where Kei is smiling, laughing, standing beside her under the soft light of a spring lantern.

Love didn't need forever.

It only needed time.

And in the time they had...

They loved with all they had—in honesty, in loyalty, in truth, and in faith.

The End.
