* In the Netflix series ''Greenhouse Academy'', there's almost literally a Love Dodecahedron, with 11 students linked by various love triangles.

* ''Series/GreysAnatomy'' features a love dodecahedron in which George loves Meredith, who loves Derek, who can't decide if he loves Meredith or Addison, who also is still in love with Derek but at one point was in love with Mark, who slept with Callie, who is married to George, who slept with Izzie, who used to date Alex, who's lusted after by Addison (and that's ''before'' you get into the {{subtext}}). Coincidentally, the best-remembered episode of the first season featured a hospital-wide outbreak of syphilis.

** Ana-Lucia filled the same role in a love square during season 2.

* ''Series/{{Pandora}}'' has one of these develop by Episode 8. We've got Tom, who's in love with Atria, who's in love with Ralen, who's in love with Jax, who's in love with Duval, who returns some form of feelings but is too deep in with his spy life to let himself fully reciprocate.

* ''Series/ConversationsWithFriends'': Frances begins an affair Nick. He still also loves his wife Melissa. Frances' ex and friend Bobbi is attracted to Melissa meanwhile, having kissed her. Later on, Frances kisses Bobbi, and expresses her desire to sleep with her again, confessing her love for her. [[spoiler:Frances and Nick break up in the end. She and Bobbi get back together.]]

** The season 13 and 14 tenners take it UpToEleven. There are only 8 people involved in the romantic drama, but ''nine'' relationships that were either serious crushes or that actually happened: Maya/Cam, Tristan/Cam, Zig/Tori, Maya/Zig, Maya/Miles, Miles/Zoe, Zoe/Zig, Zoe/Grace, Miles/Tristan and ''seven'' love triangles Cam/Maya/Zig, Tori/Zig/Maya, Miles/Maya/Zig, Maya/Miles/Zoe, Zoe/Zig/Maya, Maya/Miles/Tristan, and Miles/Zoe/Grace

* ''Series/ConversationsWithFriends'': Frances begins an affair Nick. He still also loves his wife Melissa. Frances' ex and friend Bobbi is attracted to Melissa meanwhile, having kissed her. Later on, Frances kisses Bobbi, and expresses her desire to sleep with her again, expressing her love for her. [[spoiler:Frances and Nick break up in the end. She and Bobbi get back together.]]

** And moving into season 8 adds Davis, who is in love with Chloe, and Tess, who manages HoYay ''and'' FoeYay with every single member of the cast (Clark, Lois, Oliver, Chloe, [[DatingCatwoman Zod]], [[BreadEggsMilkSquick potted plants]], [[CargoShip office furniture]], etc.).

** Faith. Definite FoeYay between her and Buffy, and she takes Xander's v-card. She is also seemingly obsessed with Buffy's sloppy seconds: in addition to Xander's long-standing crush, she tried to come on to Angel at least once, showed interest in Scott Hope, slept with Riley while she was in Buffy's body, and in season seven she slept with Robin Wood and ''seemed'' like she was going to take up with Spike.

* ''Series/{{Hannibal}}'': Will likes Alana, who likes both him and Hannibal, while Hannibal [[HoYay kinda likes Will]] and shares a surrogate daughter with him, but also has some [[ShipTease Ship Tease]] with his psychiatrist Bedelia and with Alana. Will and Alana make out once, but decide they would be bad for each other. Then Hannibal and Alana become lovers, while Will engages in a cat-and-mouse [[FoeYay "seduction"]] play with Hannibal. Margot Verger once sleeps with Will to conceive a baby. After Hannibal realises that Will wants to bring him to justice, he [[NotGoodWithRejection violently]] breaks up with him, and runs away with Bedelia to become fake married, even though he continues to openly pine for Will. Will pines for Hannibal too, and searches for him across Europe, but then breaks up with him a second time and marries Molly Foster for three years. Alana and Margot become a couple, marry and have a son. In the series finale, [[DestructiveRomance Will and Hannibal]] finally become an item. No, this show isn't a romcom.

** In series 3, Jack (who at the time had recently kissed Ianto in ''Series/{{Torchwood}}'') and Martha both have unrequited crushes on the Doctor, while the Doctor (in the guise of John Smith) romances Joan Redfern. Martha eventually gets over this and marries [[spoiler:Mickey Smith, who also seems to be over his hangups with Rose]].
