'''Basic Trope''': A man takes a younger woman that he helped raise as his wife when she comes of age.
* '''Straight''': Bob, an adult, has known Alice since she was a little girl. When she turns 15-19 years old, the two begin to court and eventually marry each other
* '''Exaggerated''': Bob begins to romance Alice when she is younger, like say [[{{Lolicon}} 8-10 years old]].
* '''Downplayed''': Bob and Alice grew up together like brother and sister. They begin going out when the younger of the two, Alice, is in her mid-20s.
* '''Justified''': Bob and Alice are from Noble Families in period setting and it is an ArrangedMarriage.
* '''Inverted''':
** [[GenderInvertedTrope Alice has known Bob since he was a little boy]]. When he turns 15-19 years old, they begin to court each other and marry.
** Alice falls in love with her adopted father and courts him when she comes of age.
** Alice and Bob are in an ArrangedMarriage in which neither had any say, and both of them are so weirded out by the age difference that they never consummate it.
* '''Subverted''': Bob begins to court Alice when she comes of age but she is so repulsed by the idea that she rejects him.
* '''Double Subverted''':
** But eventually Alice realizes that no one has ever loved or cared about her more than Bob and comes to accept his advances. Things proceed from there.
** Bob has known Alice since she was a small child, and when she turns of age, they begin courting. But Bob eventually puts a stop to the relationship, and sets her up with a nice young man. Turns out, Bob's a time traveler and this nice young man is Bob's younger self. ( ...and [[Creator/RobertAHeinlein so is]] [[MyOwnGrampa the girl]])
* '''Parodied''': Bob is a loner who can't get a date. Bob declares his undying love for Alice when she's only 5, yet she's sane enough to be weirded out by the idea. Flash forward a year, where the same declaration is made, with identical results. Repeat for fifteen years, during which Bob never ages (or change his clothes) and Alice sports the same weirded-out look on her face.
* '''Zig Zagged''': Bob is like a father to Alice. As she gets older people start to suspect that he has a romantic interest in her, and is raising her to be the ideal wife. When confronted w/ this Bob denies it, and seems squicked out by the idea. Then it turns out he has been raising her to be the ideal wife for his son, Charlie (who is 7 years younger than Alice).
* '''Averted''': Bob does not view Alice as anything more than a child and makes no advances towards her.
* '''Enforced''': The authors either lived in an earlier time [[ValuesDissonance where this was perfectly acceptable]] or wish to capture the feel of such an era [[DeliberateValuesDissonance as accurately as possible]]
* '''Lampshaded''': "Alice, would you marry me?" "Uh, you've been like a father to me for years, but whatever..."
* '''Invoked''': Bob takes up a father role for Alice specifically so that when she grows up, she'll want to marry him.
* '''Exploited''': As Alice's peer Charlie discovers IWantMyBelovedToBeHappy, he realizes the more-than-paternal role Bob plays in Alice's life and encourages her to be with him romantically.
* '''Defied''': "Marry her? You're talking about my daughter here! Of course, we're not related by blood, but still!"
* '''Discussed''': "That's a real sketchy thing Bob's doing, asking for the hand of Alice in marriage. It's like...a father asking his daughter to marry him."
* '''Conversed''': "Wait, so the hero is raising the girl so she can be his lover later? That's...uh..."
* '''Deconstructed''':
** Bob is ostracized or arrested for pedophilic behavior.
** The plan backfires since Alice now sees Bob as her older Sibling.
** The plan works, but it's questionable how much choice Alice had in the matter of marrying a man who's had that kind of authority over her.
** The plan works, but now Alice is trapped in a forced child marriage that she can't escape from lest her family murders her. And then there's the domestic abuse...
* '''Reconstructed''':
** Alice reveals that she has secretly felt the same way about Bob, and the couple then work to regain his status.
** Alice becomes of legal age when the wedding day arrives.
* '''Played For Drama''': Bob stole Alice from her brother Charlie and had him shipped off to a remote labor camp. Bob is often seen engaging in some mild IHaveYouNowMyPretty.
