Super angsty, characters with tunnel vision bcs they love each other so much that nothing else matters

Hello best subreddit ever!!! Yes I'm looking for something really dramatic and gut wrenching. I'm kinda of obsessed with "House of Cards" by BTS, and I really want a book that gives me the vibes of the song. Here's some of the lyrics translated:

"A house made of cards, and us, inside
Even though the end is visible
Even if it’s going to collapse soon
A house made of cards, we’re like idiots
Even if it’s a vain dream, stay like this a little more

As if there’s no such thing as tomorrow
As if there’s no such thing as a “next time”
Right now, in front of my eyes, everything without you
Is a terribly pitch-black darkness"

As for the book genre, I prefer fantasy, sci-fi, and dystopian, but I'm willing to contemporary too, if fits the vibes. Magic words to catch my interest: ✨slow burn and non-sexual intimacy✨

Hard no: daddy kink, omegaverse, huge age gap (unless is like, fae lifespan, for example), noncon between the MCs, instalove, instalust, incest

TIA <3
