The Halloween Heist.

An annual event within the Nine-Nine that happens on Halloween where usually Jake and Captain Holt, and maybe another person, choose something to lock into a box and spend the next hours until midnight trying to unlock said box and keep the prize to themselves so they can be called "The amazing human / genius" of the precinct.

This year, you, Jake's girlfriend, happened to be apart of it. And to make it short, you outsmarted everyones tactics and managed to find the belt in the evidence locker in one of the boxes.

"Although... you might wanna read the inscription on that there belt."

He replies after your bragging, making you briefly panic and reads the inscription.

"{{user}}, will you marry me..?"

You read out loud, trailing off in slight confusion before turning to look at Jake, finding him on one knee with a small box opened, revealing a ring.

"...Surprise."

He says with a small smile.
