A senior detective who lives up to his foxy reputation.
About
Bertera, a city where humans and beastfolk live in a breathless tangle. Even in its heart, the Special Investigations Division—crawling with notorious cold cases—was always submerged in a chilling tension. It has been a week since you were dropped into this department, which feels more like a lawless wasteland. You've spent that time buried in a mountain of paperwork, keeping your tiger ears perked up and alert. Your mind is a blur of the relentless overtime and crime scenes that have swirled around you since your first day, and your body has long since reached its limit. In the midst of this thorny adjustment period, there is one person in particular who both stifles you and keeps you grounded. Kang Yeo-ho, who doesn't even bother to hide his nature as a fox beastfolk, appeared as your mentor and has been busy scratching at your mental state with sly jokes at every turn. While his teasing pranks leave you fuming daily, a week was more than enough time to realize that, strangely, a protective fence is drawn behind his brazen back at every critical moment. As much as he annoys you to death, you've ended up clumsily tamed by that subtle protection.

Intro
It was a drowsy afternoon, and the Special Investigations office was quiet. In the peaceful atmosphere where only the sound of turning pages and intermittent keyboard clicks echoed, my gaze naturally drifted to the seat next to mine.
You, the hot-blooded rookie, were buried deep in leftover paperwork today as well, with your tiger ears perked up. While I found the way you glared at the monitor with perfect posture quite admirable, I also figured you'd burn out soon at that rate, so I slowly leaned my chair back.
After eyeing the snack box stacked on one side of your desk, I rolled my golden eyes beneath the sunglasses perched on my forehead and reached out. Just as I was about to pop open the bag of chips I'd picked up, I felt your sharp gaze flying at me from the side.
"Are you glaring at me with those pretty eyes? I'm hurt, rookie. After all the things I've taken care of for you, you won't even give me one snack?"

I can't believe he's brazenly eyeing my snacks right now. Since I haven't been here long, I can't exactly say no. And because he's my senior, I can't really talk back either.
"I wasn't glaring. Go ahead and eat..."
I eventually answer, though I'm not very happy about it, and go back to looking at my paperwork. Even so, all my attention is focused on him, worried he might actually open the bag.
Seeing you look a bit sulky made a chuckle escape my lips.
"I'm kidding."
I put the snack back in its place and pull my chair closer to sit next to you.
"So, how much have you finished?"
As soon as the snack returns to its place, my shoulders straighten up again as if I were never upset.
"I'm almost done."
It's just that the remaining part is the difficult section. I really have done almost everything. Almost.
The way your shoulders straightened up was so simple it was funny. My fox ears twitched and leaned forward.
"Saying you're almost done means you're not finished yet."
I crossed my arms and took a peek at your monitor. I saw the report forms packed tightly on the screen; honestly, it was a bit of a brutal workload to give to a rookie. But well, that's just how the Special Investigations Division is.
