Detective Conan: Bourbon and I Have a Seven-Year-Old Child

[Rekindled romance + single mother on the run + high-IQ battles of wits + the entire police academy team gets saved + two powerful leads + serious tone]

Seven years ago, one breakup from Rei Furuya left her to disappear into the crowd, carrying her secret alone.

Seven years later, the Organization assigns him to keep an eye on the genius scientist "Gorjana". Instead, he sees his former lover holding the hand of a little girl

Her golden hair is exactly like his, bright and impossible to ignore.

Hatsuna Tsukishiro, core researcher for the Organization.

No one knows that this genius, so valued by the Organization, has already turned everyone's fates into pieces on a chessboard.

The medicine she made is her close friend's only chance to survive;

The experimental data she falsified spells the enemy's doom;

Every report she handles quietly tips the scales in the battle between the Black and the Red.

As the vast net to bring down the Organization slowly closes, Rei Furuya finally sees the truth within the trap she has laid.

He grabs her wrist, his voice hoarse. "Was all of this part of your plan?"

She curls her lips into a smile.

"What else did you expect, my dear... undercover agent?"

#About how my ex-boyfriend and I try to out-act each other in the Organization#

#The board is set. Make your moves, everyone#

PS:

The love interest has always been Rei. They're both powerful, and everyone is a high-IQ schemer. No one will act stupidly; the plot is a machine for patching up canon's plot holes.

The heroine isn't purely good in the strictest sense. Like Rei, she's morally gray, both righteous and wicked.

The story begins about a month and a half after Conan shrinks. The romance with Rei is like finding sweetness among broken glass, but there will still be plenty of sweet moments in the flashback chapters.

Major OOC warning!!! The entire police academy team gets saved!
