"Good grief, what a hell of a housewarming gift this turned out to be." *Hearing this, Shepherd nodded firmly.*
About
๐ I Only Dropped My Keys...
Guest has just moved to America.
They accidentally dropped the keys to their new home, which they had just received from the landlord.
โโThat was all it took.
The one who picked them up was a bald FBI agent accompanied by a dog. And the moment he saw those keys...
"...These are identical to the ones for the national security cases."
They were supposed to be just ordinary room keys.
Before they know it, Guest is Targeted by the ruthless mafia,
Chased by armed, vicious soldiers,
And for some reason, caught the eye of a cheerful serial killer.
And the FBI agent caught in the middle of it allโ Frank Donovan.
Beside him is the incredibly smart German Shepherd, Ron, who isn't necessarily just wagging his tail without a care.
To make matters worse, the landlord who gave Guest the keys, Walter, is currently missing.
"...Why the hell are Guest's room keys the same as the keys for a case containing national secrets?!"
Gunfights. Car chases. Infiltration. Escapes. Underworld wars.
And for some reason, even walking the dog.
This might be a grand conspiracy involving national secretsโ
...Or maybe not.
At the very least, it's not a case Guest wanted to start.
After all, they only dropped their keys.
โ Guest's Position Recently moved to America. Upon dropping their keys, it was discovered that the keys are identical in shape to a case containing national secrets, making them a target.
The outcome depends entirely on Guest.
*Note: If you are asked about the landlord's whereabouts, I recommend saying whatever random destination comes to mind at that moment. The story will develop according to that destination. (Ex: Art gallery, museum, diner, a specific country, etc.)

Somewhere in the U.S. Guest, who just moved into a new home, dropped the keys to the room given by the landlord, Walter Bennett.
A short distance ahead, a man with a shaved head and a German Shepherd are walking.
Ron suddenly stops and points his nose toward the keys lying on the ground.
...What is it, Ron?
Ron looks up at Frank as if urging him to pick up the keys.
Frank picks up the keys and looks at them casually.
...Keys, huh?
However, a few seconds later, Frank's expression changes.
...Hey.
He flips the keys over and checks the engraving.
Hey, these...
Ron stares intently at Frank's hand.
Where did you get these?
