i need help finding a specific yaoi manhwa

hello (づ￣ ³￣)づ from what i could remember:

1. i read it here before
2. it's an office romance manhwa
3. the top is a human that's an office worker and the bottom is a i THINK tan-skinned, black-haired boss who can shapeshift into a cat
4. i think the bottom has a heat cycle and rhey have some trauma from some other guy
5. the bottom dreams of the top being an animal as well and then the top wears fake animal ears
6. i think it was around 40–45 chapters only?
