Heat & Content Terms {#heat}

Open door
Scenes of intimacy are shown on the page (you’re in the room with the characters).
In a sentence: “This is open door — expect on-page spice.”

Closed door
The story implies intimacy off the page. The door closes; you pick up after.
In a sentence: “Sweet but closed door — lots of chemistry, no explicit scenes.”

Fade to black
A specific kind of closed door: the scene begins, then “fades” to the next morning.
In a sentence: “They kiss, it fades to black, next chapter is breakfast.”

Spice / Heat level
How explicit/frequent the intimate content is. Many readers use a chili scale:

• 🌶 = mild/tease
• 🌶🌶 = open door, lighter detail
• 🌶🌶🌶 = explicit, standard
• 🌶🌶🌶🌶 = very explicit/frequent
  (Scales vary; reviewers usually explain their meter.)

• Level 1 (Extra Mild): Kissing and touching, with sex happening “behind closed doors”.
• Level 2 (Mild): More kissing and touching, with increasing sexual tension. Sex is often described using euphemisms.
• Level 3 (Medium): Contains some detailed and realistic sex scenes, though they are shorter and less frequent. The focus is still on the plot.
• Level 4 (Hot): Features detailed and graphic love scenes throughout the book, with intimacy playing an important role in the plot.
• Level 5 (Extra Hot): Explicit and frequent sex scenes, possibly including erotica, multiple partners, or kink. 

Content warnings (CWs) / Trigger warnings (TWs)
Heads-up for potentially difficult topics (violence, grief, etc.). Meant to help you opt in or out.
Tip: Look for a short CW list at the front or at the end of reviews.

Consent / Enthusiastic consent
Stories that clearly show characters wanting what happens and checking in. Reviewers call this out as a positive.

Dark romance (heat/content label and subgenre)
Leans into morally messy characters or heavier themes; expect higher heat and more intensity. CWs are common.

Reader & Community Lingo {#lingo}

HEA / HFN
“Happily Ever After” / “Happy For Now.” Signals how the ending feels.

MMC / FMC
Male main character / Female main character. (You’ll also see MM/FF/etc. for pairings.)

TBR
“To Be Read” pile/list.

DNF
“Did Not Finish.”

ARC
“Advance Reader Copy” (early copy for reviewers).

KU
Kindle Unlimited — a subscription library that some titles rotate in and out of.

Trope
A familiar story pattern or setup (friends-to-lovers, only one bed). Not a bad word! Readers use tropes to find what they enjoy.

Angst
Emotional turmoil (miscommunication, past wounds) before the resolution.

Banter
Playful, flirty dialogue; often a rom-com hallmark.

Spice meter
Short-hand rating for heat level (see the chili guide above).

Relationship Tropes {#relationships}

Grumpy / Sunshine
One broody, one bright and bubbly. The contrast is the charm.

Enemies to lovers
They start on opposite sides (rivals, grudges), then fall for each other.

Rivals to lovers
Less hatred, more competition (coworkers, classmates, athletes).

Friends to lovers
Existing friendship turns romantic.

Second chance
They had history (exes, almosts), reunite later.

Forbidden romance
They shouldn’t be together (rules, families, careers), but… sparks.

Age-gap
Notable age difference between consenting adults; tone ranges from tender to taboo-adjacent.

Why-Choose / Reverse harem
One heroine with multiple love interests, and she doesn’t choose just one (consensual poly).

Found family
A circle of friends/teammates who become each other’s home and support system.

Morally gray (usually MMC)
A lead who isn’t a pure “good guy” — does questionable things, but has lines they won’t cross (often very protective of the love interest).

Plot / Setup Tropes {#setups}

Forced proximity
They’re stuck together: road trip, snowed in, coworkers on a project.

Only one bed
Exactly what it says; often comedic, always cozy/tense.

Fake dating / fake marriage
They pretend to be together for a reason — and then feelings happen.

Marriage of convenience
They agree to marry for practical reasons (business, family, survival) → real romance grows.

Secret relationship
They’re together, but hiding it (workplace rules, family drama, media attention).

Bodyguard / Protector
One keeps the other safe; protective energy is part of the appeal.

Hurt / Comfort
One character is physically/emotionally hurting; the other cares for them.

Slow burn
Romance builds gradually; the payoff comes later. Tension = the point.

Insta-love / insta-lust
Attraction or feelings hit fast; the story explores fallout and commitment.

Subgenres & Settings {#subgenres}

Romantasy (fantasy romance)
Magic, courts, monsters, quests — with a central love story that matters to the plot.

Paranormal romance (PNR)
Supernatural leads (wolves, vampires, witches) and pack/coven politics.

Monster romance
Non-human love interests; ranges from cozy to campy. Consent/communication are usually spotlighted.

Mafia / Billionaire
Power, danger, luxury; high stakes and protective leads.

Sports romance
Athletes or teams; rivalry, training, and locker-room banter.

Small-town / Cozy spice
Community vibes, festivals, family — still open door, just warmer tone.

Historical (open-door or closed-door)
Regency/Victorian and beyond. Some are closed-door; others are openly sensual.

Romantic suspense
Mystery/danger woven with the romance; page-turning + protective energy.

Rockstar / Music industry
Bands, tours, fame, and messy hearts.

Workplace / Office
Colleagues (or boss/employee with clear consent); banter + proximity.

Holiday / Seasonal
Festive settings (winter holidays, summer beach reads) with on-theme tropes.
