Need help finding a manhwa

I’ve been searching for so long but I still haven’t found the name of this one manhwa, the only things that I know is:

- the couple; a black panther guy, and this human.
- The animal people can switch into their animal state when aggravated(?)
- they’re in some type of army but have a dislike towards humans who join??? This might be wrong
-they live together at one point cause they’re partners in a unit, I’m pretty confident that they lived together at one point

I honestly forgot but I think they took it down in this site, kinda saddy, but it is what it is :(

Id really appreciate if someone has any idea of what it is
