When a person or couple fake a romantic relationship, and then fall in love.
There are two major variants, depending on who is in on the deception. In the solo deceiver variant, one of the couple is trying to fool the other about their feelings. A classic example is when a Gold Digger falls in love with their mark. This can resolve in various ways — the deception is undiscovered and we end with a loving couple; the deception is discovered and the deceiver has to reestablish trust to achieve the happy ending; or the deceiver is discovered and rejected and suffers a romantic failure as well as the failure of their initial plan.
In the two deceiver variant, both participants know the relationship to be fake. They might pretend to be dating, or announce an engagement with no intention to actually marry, or marry without intending to live as a married couple. There must be an element of deception — the couple intend at least one person to believe the relationship is real. Common motives are for one of the couple to gain legal status (citizenship, health insurance coverage, freedom from a parent) or because one of the couple has lied about being in a relationship and now needs a stand-in for the fictional partner. This variation usually ends happily for the couple.
This trope is the intersection of Fake Relationship (a fake romantic relationship) and Becoming the Mask (what started as a facade becomes real). Overlaps with The Beard if the Fake Relationship began for the purpose of perpetrating a deception.
The two deceiver variant overlaps with Marriage Before Romance, and Marriage of Convenience. Marriage Before Romance does not require deception (e.g. people understand that in an arranged marriage, the couple do not initially love each other) and this trope allows relationships other than marriage. A Marriage of Convenience usually involves deception, and so becomes this trope if the couple fall in love.
The single deceiver variant is a subset of In Love with the Mark, when the mark was to be targeted romantically rather than, for example, targeted for assassination. The romantic option of The Bet frequently leads to this trope. There is also overlap with SexFace Turn, but this trope does not require sex, and that trope does not require deception.
Not to be confused with Fake-Real Turn, where it is some sort of organization which is faked.
As an ending trope, spoilers marked and unmarked are abundant in this page. You Have Been Warned.

- Princess Jellyfish: Shoko Inari pretends an (aggressive) romantic interest in Shu, to use his political influence to advance a real estate project. She realizes (after he's seen through her wiles) that she has fallen for him. By this point Shu distrusts her completely, so no relationship ensues.

- Nisekoi basically revolves around this trope, with the main characters — Raku and Chitoge — paired off by their fathers, good friends and yakuza bosses, to prevent a bloody feud between their gangs. (The rank-and-file gang members are not in on this deception.) And that was after both teens got off to a bad start when Chitoge accidentally bumped onto Raku, causing him to (temporarily) lose his precious pendant, given to him by a long-forgotten childhood love. As much as they openly claim to hate each other's guts, they soon discover that their fake romance is slowly becoming real.
- In Runaways, Karolina and Xavin's relationship initially began as a ruse to try and end the war between their respective species, but over time, they grew to care about each other.

- Roadqueen: Eternal Roadtrip To Love revolves around Leo and Vega "fake-dating" for a week. It starts as a way for Leo to prove she can be a great girlfriend and "decent lesbian" so Vega will return her beloved motorcycle, but as the week goes on, it becomes clear that they're developing real feelings for one another.
- A very common fanfic trope in general. Every piece of media with a significant number of fanfics will undoubtedly have at least one of these somewhere.

The plan goes off without a hitch, although the man does end up getting a crush on the woman (Parker Pyne's assistant).
- A similar plot is used in "The Case of the Discontented Husband", but it goes completely wrong as the man falls head over heels in love with Parker Pyne's assistant and says so in front of everyone (she herself has no feelings for him, since it's just another job to her).

- Subverted in Malcom in the Middle: A girl who has been focusing on maintaining a high GPA at the expense of all else hires Reese to be her prom date so she can experience some social interaction. Over the course of the episode, Reese is a perfectly charming gentleman, apologetically going off-script to defend and compliment the girl, and even talking about how something that starts fake can lead to something real... but it turns out all the stuff about it no longer being an act was just part of the act, and he abandons her when her time is up.

He immediately regrets it, even before he finds out it was all true.

That said she later admitted that "I learned to love him, more than I had ever loved before or after."
