The silence in the office after hours was a different creature than the daytime bustle. It was a watchful, heavy quiet, broken only by the hum of the server rack and the distant, rhythmic click of Miyako’s keyboard. A spreadsheet glowed on her monitor, but her eyes were fixed on the security camera feed on her second screen. It showed the front entrance, now dark and empty. He had left an hour ago, after another one of his “visits.”

You.

That’s all she ever called you in her head. A pronoun, a placeholder for the void that had suddenly taken human form and walked back into their lives. Aqua and Ruby’s biological father. Ai’s mystery man. The ghost in the family photo.

The twins had found you. That was the official story they’d presented with a chilling, rehearsed calmness that still made her shiver. A product of their own dogged, internet-age detective work, they said. Aqua with his cold, analytical precision. Ruby with her intuitive, desperate hope. They’d tracked down the spectral figure from their mother’s past and, against every instinct Miyako possessed, had wanted to let you in. And she, the woman who had spent fifteen years building a fortress of normalcy around them, had agreed. Shared custody, even. On paper. In reality, it was a supervised excavation.

She minimized the spreadsheet and opened a different file. Not a company document. A private one, encrypted and buried. It was a dossier, her dossier. At the top was the single word: YOU.

Section One: The Story with Ai. The facts were sparse, gleaned from fragments of the twins’ research and your own carefully measured, infuriatingly vague admissions. A young, dazzling Ai Hoshino, on the cusp of superstardom but achingly lonely. A chance encounter? A deliberate pursuit? You were older. Not by a grotesque margin, but by enough to suggest experience, perhaps stability—a commodity Ai had never known. It had been intense, secret, and brief. Then, you were gone. Vanished before she even knew she was pregnant. The timeline placed your disappearance roughly nine months before the twins’ birth. The coward’s exit, or something more calculated?

Section Two: The Disappearance. This was the gaping wound in the narrative. Where had you been for sixteen years? Your answers were polished, reasonable: work took you overseas; you were unaware of the pregnancy; by the time you learned of Ai’s fame and subsequent tragedy, the children were already with Miyako. You spoke of regret, of a shame that kept you away. She believed the regret. She did not believe the shame was strong enough to have truly stopped you from looking. A man who could find his way back into his children’s lives after they sought him out could have found them sooner. Unless he had a reason not to.

Section Three: Ai’s Death. This was the question that turned her blood to ice water every time you smiled at Ruby. The official report was a deranged, obsessive fan. Case closed. Ichigo—her vanished husband, the man who had loved Ai with a desperate, tragic purity—had never accepted that. He had spent years hunting a shadow, a specific man he believed was the true architect of the tragedy. And now you were here. The timing of your return was… convenient. The investigation was cold. Ichigo was a fugitive memory. The twins were vulnerable, seeking roots. You presented yourself as a severed root, willing to be grafted back on. Miyako’s mind, honed by years of managing fragile egos and spotting contractual loopholes, circled the dreadful possibility. Was the man Ichigo hunted now sitting in her living room, drinking her tea?

Section Four: Motive. This was the most critical, and the most opaque. What did you want? Money? The twins, especially Ruby, were on their way to significant wealth. But you seemed comfortable, your finances opaque but not desperate. Influence? You showed no interest in the industry, in their careers. You listened, you asked gentle questions, you offered no advice. It was parental, almost. And that was the most terrifying possibility of all. That you simply wanted them.
