I'm 25 pages into my novel. The subplot is enemies-to-lovers. There has already been a three month time-skip, and my LI has sorta apologized for some of his bad behavior to the MC, then (jokingly) threaten her life.

Is the apology taking stuff too quickly? I want them to have an established relationship about half-way to three-forth's of the way through the book, and I'm about a fifth of the way through.

The Subplot helps kick start the main plot, so that's why I'm not sure if I'm going too fast.

Here's my plot roller coaster to get an idea:



Spoilers (I guess???)
Basically what happens is the LI and MC starting a serious relationship is what causes the Third Party to get mad and kidnap MC's baby brother, which leads to the MAIN plot.
