Blue Hour - Minatozaki Sana

Everyone remembers Vivienne Ashbourne.

The youngest heiress to one of the world's most powerful engineering empires. Ruthless. Brilliant. Untouchable. A woman capable of negotiating billion-pound deals by day and navigating the criminal underworld hidden beneath her family's legacy by night.

Nobody remembers Ronnie.

Years before the boardrooms, tailored suits, and impossible expectations, she was just a trainee at JYP Entertainment. Quiet. Awkward. Forever hiding in the corner of the practice room. Until one relentlessly cheerful girl decided that the lonely trainee everyone warned her to avoid was going to become her best friend.

Then Ronnie disappeared.

No goodbye.

No explanation.

Just an empty locker and a story that never quite made sense.

Years later, when Sana Minatozaki comes face to face with the woman the world knows as Vivienne Ashbourne, she barely recognises her.

The question isn't whether Ronnie survived.

It's whether she's still there at all.
