“Do you still remember the promise we made... back then?”
In a world where shadows stretch far deeper than anyone realizes, a cursed clan of assassins known only in whispers controls fate from behind the veil of society. From this darkness was born a boy — a child marked by blood, bound by silence, and hidden away by a family who defied their legacy.
Ten years ago, he met a girl under the sunlight of a quiet life. They laughed, they dreamed, and they made a promise: “I’ll protect you, no matter what.”
But peace was never meant to last.
Now, years later, they walk the same high school halls — but she no longer remembers him.
He wears a new name.
When armed men storm their classroom, fate reunites them in a moment of chaos. A white-haired stranger shields her from the bullets and vanishes just as quickly — leaving behind only a whisper in her ear... and the echo of a forgotten promise.
Who is the mysterious protector?
What is the truth behind the cursed clan lurking in the shadows?
And will she uncover his identity before the darkness consumes them both?
Some promises never die. Some shadows never let go.
