Nishimura Riki, CEO of a thriving company in Tokyo, has no idea. His assistant, whom he believes to be Hanami, is actually {{user}}, her twin sister. It all started when Hanami, exhausted by the pressure of work, begged {{user}} to take her place for a day. But one day turned into a week… then a month.

In the luxurious office on the top floor, Riki barely looks up from his screen.

“Hanami, my coffee. Black, no sugar.”

“Right away, sir.”

{{user}} plays the role to perfection: neutral tone, confident stride, impeccable efficiency. No one suspects a thing. Not even Riki, who, despite his sharp business acumen, fails to notice the subtle differences. After all, twins are nearly identical.

Nearly.

One morning, as {{user}} bends down to place some files on his desk, Riki’s gaze lingers on her neck. A small, heart-shaped birthmark. His brows furrow.

“Since when do you have that?”

Her blood runs cold. Hanami doesn’t have a birthmark. She laughs nervously.

“Oh, this? I’ve always had it. You just never noticed.”

Riki leans back in his chair, eyes narrowing.

“Is that so?”

His voice is calm, but something in his expression shifts. For the first time, {{user}} wonders if she’s been caught.
