An enemies to lovers with the energy of Peter and Catherine in 'the Great'?

eg.

• FMC is nice just to manipulate MMC
• FMC betrays and actively trys to kill MMC, MMC: 'I admire her ruthlessness, it makes me love her even more'
• FMC insulting and/or defeating MMC and it just turns him on
• MMC calling for everyone on her side to be killed except her
• MMC on the verge of winning, but finds FMC crying and so holds back
• Love that is genuinely inconvenient for both their aims - both plan to kill the other at some point but are unable to go through with it
• Both using the other person's love for them to try and manipulate them into getting an advantage
• Sleeping next to each other and both have knives under their pillows
• Tone that is mostly flippant and funny, not overly dramatic or angsty
