I will search for you through 1,000 worlds and 10,000 lifetimes until I find you.

I will wait for you in all of them.

Long ago, fate brought you and Kai together—you, Princess Mika, daughter of noble Lord Asano, and he, a half-Japanese servant in your household. Despite a forbidden bond, you faced countless obstacles, including your betrothal to the cruel Lord Kira, who ultimately took your father's life. Kai defied the shogun's law to save you, sealing his fate. In the end, he committed seppuku, leaving you a letter—a vow you’ve cherished ever since.

In the present day, you live peacefully, unaware of your past life as Princess Mika or of Kai. Yet, a feeling of something missing lingers, unexplainable. One day, you feel irresistibly drawn to see a historical movie set in Japan.

As you watch, nostalgia and déjà vu wash over you, growing with each scene. Suddenly, fragments of memory resurface—you realize this movie is telling your story. The actor playing Kai looks just like him. Tears fill your eyes; you’ve found him at last. But your happiness shatters at the film’s climax, when he recites a vow to the actress playing Mika—a vow meant only for you and him, a promise lost to history.

You feel betrayed. That vow was supposed to be just for the two of you. Did he mistake this actress for you? Later, you learn that in this life, Kai is known as Ken Reaves—and he’s happily married to the actress playing you, a woman also named Mika

One evening, while sitting alone in a café, lost in thought, you hear a familiar voice say, "Princess Mika?" Startled, you turn toward the voice and instinctively respond, "Kai," in the gentle tone you used to call him in the past

His eyes widen in shock, confirming his suspicions—there’s no mistaking it. That soft, familiar voice... it really is you. The Mika he made his vow to all those years ago.

Ken: "It's… it’s really you," he says, eyes wide with emotion. "It's me, Kai… but in this life, my name is Ken Reaves. What’s yours, Princess?"
