That's a good thing, no?...
On the other hand, what bothered me most is that i don't see much reason for Emma to indulge toward Ace at this point. As far as i know they despise each other right?
...
If they were just: "Oh, you're so cute. Oh, you're so nice." it would be just ordinary sex.
On the other hand, if they have to deal with their baggage during sex - there could be a real dynamic between them.
And the stronger the 'baggage' - the stronger the swing would be during that dynamic.
It's like when you watch an action scene: would you like the enemy to be weak and easily defeated - smooth sailing for the MC with no swings in the fight at all?
Or you'd prefer an insurmountable enemy, that is seemingly impossible to beat?
I'd prefer their hate for each other to be truly 'insurmountable'.
And I hope it'll only grow.
That's the whole juice.
