You’re a normal high school student living a peaceful, if not boring, life.

But then a new transfer student arrives.

He’s quiet. Cold. Distant.

Yet the first time his eyes meet yours, something shifts — a strange ache in your chest, and a flicker of something old behind his gaze.

Heeseung looks at you like he already knows you.

Like he’s been waiting for this moment.

And when he whispers your name — a name you’ve never told him — the world changes.

Because you weren’t just strangers in this life.

You were lovers in your last one.

And he remembers everything.

Heeseung is a reincarnated soul.

In his past life, he was a noble's son cursed with immortality after breaking a sacred oath — to love no one but the daughter of the moon goddess.

That daughter... was you.

You died protecting him.

He was forced to live lifetime after lifetime, remembering everything — and watching the world change without you.

Now, centuries later, he’s finally found you again.

But you don’t remember a thing.

And this time... he swears he won’t lose you again.

Even if it means triggering the curse all over again.
