Love Father, Love Son
Yeah, but Monica, do you really want to be in a relationship where you can actually use the phrase, "That's not how your dad used to do it"?—Phoebe, Friends
Love Father, Love Son is a love trope in which a person who can't have the person that they love for one reason or another winds up falling for their progeny, possibly because there's a strong resemblance in looks or personality, or maybe just because.

Later, Clow Reed is reincarnated as Fujitaka Kinomoto, and Yue's alternate form Yukito (and later Yue himself) falls in love with Fujitaka's son Touya. Follow that? (For added madness, Clow had intended for Yukito to fall in love with Fujitaka's daughter, the titular Sakura.)
- In Kodomo no Jikan, this combined with Wife Husbandry and Kissing Cousins, is what Reiji's doing with Rin. He fell in love and was with her mother, but then she died of lung cancer. Now he's raising Rin to replace her.

- The Japanese novel Thousand Cranes plays this straight when the main character sleeps with his deceased father's ex-lover, then Gender Flips / inverts it when he falls for that woman's daughter, leading to a Did They or Didn't They? situation at the end. (For added fun, someone's trying to set him up with a third, unrelated woman while all this is going on.)
- In the Denouement of Edgar Rice Burroughs's Warlord of Mars, Thuvia's hopeless crush on John Carter is showing every sign of being cured by meeting his son Carthoris. (Things go wrong so that she and he get their own book, Thuvia, Maid of Mars.)

- In Friends, Monica is attracted to Richard's son. Initially.
- On Angel, Cordelia went through seasons of Will They or Won't They? with Angel, only for Angel's suddenly grown son Connor to take an interest in her too. They wind up having a one-night stand, and Cordelia gets pregnant. Played with because Cordelia is secretly possessed by the season's Big Bad when they had sex, and made creepier because her pregnancy is basically just to give the Big Bad a new body, making this Parental Incest, sort-of-maybe.
- In The Bible, Joseph manages to barely resist an affair with Potiphar's wife. He later marries the daughter of a man named Potipherah, which is similar enough to Potiphar that some believe them to be the same person. (Averted in the Muslim version of this story, where Potiphar's wife is more sympathetic and eventually marries Joseph herself.)
- One Jewish tradition holds that Potiphar's wife wanted to sleep with Joseph because she knew from divination that they were destined to have descendants together—misunderstanding that those descendants would be through her daughter.
- Joseph's brother, Judah, inverts this trope: in accordance with the law of levirate marriage he winds up marrying Tamar, the widow of his two older sons.
- Agatha Christie's play Go Back For Murder (based on her novel Five Little Pigs) is about a young woman, Carla, who upon coming of age re-opens the investigation on the murder of her father 16 years ago, which was pinned down on her mother Carolina (who has died in prison). The solicitor she goes for help remembers the trial and having a youthful crush on Carolina; by the end of the play, he and Carla get together. (This plot element was not present in the original book, where Carla goes to Poirot instead of the solicitor - as she used to do, Christie wrote Poirot out of the play adaptation.)
- In Avalon Code, Mayor Georg married the granddaughter of his first love.
- In Devil May Cry 3, Dante encounters Nevan the Lightning Witch, a devilishly curious woman whose words sounds like she's a prostitute willingly offering to get into Dante's pants (she's either a succubus or leanashe; the game doesn't clarify). Her dialogue ("Your father was a handsome devil. But you're no slouch yourself.") implies that she also had lusted after Dante's father Sparda in the past. Of course, the fans got a bit carried away with all of the Foe Yay/Ship Tease and as a result, Dante/Nevan enjoys a good deal of popularity among Dante's naval fleet.
- In Agarest Senki, Ellis is twelve when Leonhardt rescues her from certain death, and doesn't get a chance to grow up before he makes his Heroic Sacrifice. Being a long-lived High Elf, she settles for his near-identical Great Great Grandson Rex.
- Bizarrely inverted in the second Shadow Hearts game. Karen is in love with Yuri, but he can never return her feelings because he loves Alice. The good ending sends Karen back in time, where she meets and falls in love with Yuri's dad.
- Legend of Dragoon apparently tries to bridge this with a Love Dodecahedron, since Rose, who was involved with Zieg ten thousand years ago begins to fall for Dart, his son and is honest with herself about why. Things only get more complicated when Dart becomes involved with someone else and it's revealed that Zieg is still alive (and was happily married for at least a little while).
- The Simpsons: Mr. Burns' illegitimate son was the result of a One Night Stand with the daughter of his old college crush.
Burns flashes back to the outdoors of the 25th Yale reunion feast of his Class of 1914. A much younger C.M. Burns sees his unrequited love of his college years, Mimsy Bancroft, a middle-aged woman staring back at Young Burns. Young Burns becomes wide-eyed as the narration goes on. "Of course, by then, Mimsy had her share of wrinkles and a grey hair or two, but my adoring eye saw past those minor imperfections - to her 21-year-old daughter, Lily."
- In one episode of The Pirates of Dark Water, and elderly alchemist reveals that she was Ren's father's ex-girlfriend. She never got over losing Primus to Ren's mother. She later used a potion to restore her youth and blackmailed Ren into marrying her in a crazed attempt to reclaim her past happiness. Sadly, the potion backfired on her—likely because she used a drop of Dark Water to make it—and she suffered Rapid Aging. When Ren tries to apologize for his father jilting her, she absolves him and his father of blame saying that she was the one who couldn't let go of the past.
- Irish poet W.B. Yeats proposed to Maud Gonne multiple times before proposing to her illegitimate daughter Iseult, who also turned him down.
