Slow Burn
Tension stretched across the entire page count.

Slow burn is patience as a design choice. The characters circle for most of the book, and every near-miss is deliberate. Done well it makes an ordinary moment — a hand, a name said properly — land harder than any grand gesture.
Where to start: Longer books serve this best; a slow burn in 250 pages is just a delay. Series romance can stretch the tension across multiple volumes if you have the stamina for it.
