I Want to Be Big Sister's Puppy Today Too

[No logic, original headcanons, OOC warning, older-sister-and-puppy dynamic, dog-training fiction, written for personal tastes]

Matsuda Jinpei and Furuya Rei are friends. Ever since police academy, they've shared a secret: they both like the same person, and both want to be that person's puppy.

Big Sis doesn't need a lover. She just needs puppies.
