Enemies-to-lovers where invincible FMC is guarding a treasure and MMC tries to get it

So I had this weird dream last night, it was quite specific. Naturally I was wondering if something like this exists in the real world.

Basically the setting was like this, there is this treasure that's really desirable, but it's guarded by some invincible goddess/amazon type FMC. Not a tribe, just this single woman. She's been doing this for quite some time. Now the MMC obviously wants to get to that treasure, but he bears no ill will towards FMC - basically she's just an obstacle on his way to whatever he needs the money for.

So he tries little skirmishes here and there, fighting her for it, but gets nowhere because she is, in fact, invincible. Over time he builds up a kind of grudging respect for her, even though he is foiled at every turn. In the end, he goes for his ultimate assault which actually manages to hurt her a little bit (in my dream, this was hitting her on the head with a really heavy book, but I'm willing to allow for some editorial freedom on this one). She breaks down crying, which bewilders and shocks MMC. Out of inexplicably feeling sorry for her, he turns to her and tries to comfort her.

Well, it turns out that she is not so much hurt physically by his attack, but is worn down by sheer frustration that every person she meets just wants to get to that treasure and is attacking her for it. Although she knows it's not personal, she still feels like she is not seen as a person, which over time has made her feel pretty jarred.

Now MMC is torn between feeling guilty and sorry for her on the one hand, and still wanting to get to the treasure on the other hand. And also there is this growing sense of wanting to be with her, but at this point it's not clear to him whether this is out a sense of respect and attraction to her, or if it's just a different way of getting to that treasure somewhere down the road... I sense a big internal conflict coming up.

I know it's pretty specific, but I'd be very much down to read something like this. Any recommendations? Thanks a bunch!
