Romance
Instant attraction is tidy. Also a bit dull.
The more interesting version is when desire has to make room for work, pride, bad timing and the rest of ordinary life. Someone has a shift to finish, a mortgage to pay, a reputation to protect, and suddenly the feeling has somewhere to go. That’s where it starts to look believable.
Romance can be very good at this, when it lets attraction be inconvenient instead of effortless. Not less intense. Just harder to ignore.

A bit of friction helps, but too much and it stops being romance and turns into admin. There’s a narrow line between “this matters” and “why are these people still in the same book”. The useful bit is usually the compromise. Someone notices they’re being altered by the other person before they’re ready to admit it.
