A Blade Forged from Hate, Reborn from the Cocoon

Looking for Novels with a Pure-Hatred Vibe from Your Bookshelves!

I love them and hate them! They're so awkward around each other, always sabotaging each other, but still have to act nice to one another in front of outsiders! Give me that pure love-hate, enemies-who-can't-stop-loving-each-other vibe! Anyone know something like the vibe of Paper Bride 7?!
