Serious suggestion.
Write that in the epilogue : they reincarnated as babies, and one tell the other, "Soooo, what is the score again? / 489-486 I am winning by 3 life-victories"

My angst maaaay or may not have been responsible for making the foundation of the relationship a hatred-fueled duel where one side shatters the other's dueling weapon and makes her a servant. Plus, they would be both holding back at the start, so they have to settle the score in the end, right? >:)
Enemies-to-lovers is one of my favorite tropes!
...I have read too much toxic romances and Shoujo mangas...
