History UnresolvedSexualTension / LiveActionTV

* ''Series/StarTrekTheNextGeneration'': Captain Picard and Doctor Crusher have UST from the very first two episodes (wherein he nearly has a stroke upon first seeing her and then again when she comes on to him while under the influence) to the last (wherein they eventually (in what may be an averted alternate future) marry, and then divorce, though she keeps his name). This gets particularly bad when they are telepathically joined in season 7, discover and openly discuss the UST, and still choose not to resolve it.

* ''Series/{{Angel}}'': Angel and Cordelia and Wesley and Fred absolutely torture the audience with this for years. Both cases are finally resolved in the final season [[spoiler: with the deaths of both women. Cordelia and Angel ''never'' get to have sex, and it's unclear if Fred and Wesley ever do (she has a line while she's dying about "finally" getting him up to her bedroom, but they might have slept together at his place).]] This could fit with all the A.I deaths on this show. [[spoiler: Doyle died right after kissing Cordelia, after pining after her for his entire time on the show, Fred died only one episode after finally getting together with Wesley, and Wesley died right as he was beginning to get along with Illyria.]]

* ''Series/BuffyTheVampireSlayer'':
** Buffy and Angel are the staple for this trope. They have it in most — if not ''all'' — of their interactions since they [[CantHaveSexEver Can't Have Sex, Ever]] or else Angel turns evil or the world ends [[spoiler: (literally)]]. The entirety of Season 3 was just Bangel UST climaxing in a single orgasmic KissOfTheVampire.
** Buffy and Spike in the latter part of the series. It was ''officially'' resolved in S6, then back again throughout all of S7 and [[spoiler: continued in the comic continuation until it's finally resolved in S10]].
** There was sexual tension between Buffy and Xander, especially in the second half of season two, although it largely went away as the series went on.
** Buffy and Faith. The LesYay between the two was through the roof, especially in Who Are You?, where [[GrandTheftMe Faith-in-Buffy's body]] takes a bath as the first thing that she does after the switch.

* ''Series/{{Degrassi}}'': Plays with this whenever a pairing is not put into effect immediately. Clare and Eli's UST is certainly the most recent.

* ''Series/QueerAsFolk'': Positively runs on the [[BuffySpeak unresolvedness]] of Stuart and Vince's relationship. They are best friends from childhood, and Vince at least has been madly in love with Stuart for years, and as the series progresses, Stuart seems to reciprocate [[JerkassWoobie in his own way]]. They kiss, dance together, hold hands, and at one point even make it as far as the bedroom before stopping the situation from progressing any further. This hesitation is implied to actually ''stem'' from their intense feelings for each other, as they both seem to feel that actually having sex would reduce their relationship to the same level as Stuart's constant one-night-stands. As of the finale [[spoiler: they appear to be in a contented quasi-romantic relationship, but whether they have actually done the deed is left ambiguous.]]

** Head Adelle Dewitt and her [[NumberTwo head of security]] Laurence Dominic ooze UST during their morally grey [[PowerWalk power walks]]. At least, until: [[spoiler: he was revealed to be a spy. She sounds a ''lot'' like a jilted lover when chewing him out.]]

*** Caitlin Snow had this with "Jay Garrick" in Season Two, after her husband Ronnie Raymond died in the Season One finale. They kissed at Christmas and were vaguely implied to be dating afterwards until "Jay" died. Then, it turned out "Jay" was actually Hunter Zolomon aka Zoom, BigBad of Season Two. Once Caitlin learned that, she wanted nothing to do with him. Zolomon tried to get her to love him again by kidnapping her and trying to invoke StockholmSyndrome, but after she rejected and abandoned him to return to Team Flash, he gave up on that and treated her as another enemy.

* In ''Series/{{Hunter}}'', partner LAPD detectives Hunter and [=McCall=] are obviously attracted to each other, and even admit that themselves, but manage to keep their relationship on a professional, JustFriends level, while dating other people. At least, they manage most of the time -- one episode reveals that they actually did sleep with each other once.

* ''Series/{{Merlin|2008}}'': Has this with pretty much all of its main characters at some point in time, although the most persistent/popular ones seem to be Arthur & Merlin and Arthur & Gwen. [[spoiler: Arthur and Gwen's OfficialCouple status gets firmly resolved in the series 4 finale when they get married.]]

* Series/TheWalkingDead all but ignored UST for it first three and half season's except for a few [[ShipTease teases]]. However the back half of season 4 included plenty of tension between Daryl/Beth and Rick/Michonne and a whole new relationship forming between Bob and Sasha.
* ''Series/{{Warehouse 13}}'':

* ''{{Series/Survivors}}'': Anya and Tom have this for most of the series, having a clear mutual attraction which they don't act on. Finally {{they do}} sleep together when everyone seems about to die.

** Penny and Leonard were the King and Queen of this trope early on, but they [[TheyDo move past]] [[OfficialCouple it eventually]].

** The title character and Sarah. 'Nuff said. TheyDo mid-way through the third season and don't look back.

** Kurt and Blaine was FINALLY resolved in "Original Songs." [[spoiler: [[TheyDo THEY DO]], [[ThisIsForEmphasisBitch BITCHES]].]]

* ''Series/MurdochMysteries'': UST is an apt description of the relationship between Detective William Murdoch and their Station House's Pathologist Dr. Julia Ogden, particularly in the first several seasons. Each of them in their own ways contributes to the difficulties; William seems somewhat lacking in social skills (such as dancing) and [[CantSpitItOut has trouble telling Julia how he feels]], while Julia is torn by her professional ambitions and ambivalence over motherhood in the face of his desire for a family. This is made worse by the Victorian/Edwardian setting and the necessary restraint needed by social standards of the time, as the UST was just as strong (if not stronger) whenever their on/off relationship was actually on. [[spoiler: It was at its highest possible level during season five when Julia was ''married to another man'' but the UST was eventually resolved when her husband pulled an I Want My Beloved To Be Happy and told her to be with William. Julia and William rekindling their romance closes the season. In season 6, the tension is back as they are together but unwilling to commit adultery when Julia goes through the unavoidable scandal of her divorce, capped by the murder of her husband, for which Julia was initially convicted!]] Eventually [[spoiler: in season 8]], TheyDo, but [[EarnYourHappyEnding boy howdy have they earned it]].

* ''Series/TwentyFour'': Barrels of it between Jack and Renee on the new season. WordOfGod confirms that the two will hook up in season eight. [[spoiler:[[DeathBySex With sexy results.]]]]

* ''Series/TheLordOfTheRingsTheRingsOfPower'': Halbrand and Galadriel bicker like an OldMarriedCouple from the moment they met, but also share a lot of vulnerable moments. Unfortunately, their sexual tension will stay forever unresolved, because [[spoiler:Halbrand is also Sauron in disguise]].

** Damon and Bonnie. They had a few tense scenes in Seasons 1 and 2, though they both [[FoeRomanceSubtext openly hated each other]]. It gradually faded as the series went on until Season 6, where the first few episodes were nothing but [[BelligerentSexualTension UST-filled Bamon bickering]]. In Season 7, the UST gets charged {{UpToEleven}}. Sometimes you even catch them staring at each other's lips.

* ''Series/{{Bridgerton}}'': The infamous main focus of season 2's romantic leads, Anthony and Kate. Anthony tries his best repressing his feelings for Kate due to not only his vows of not to [[MarryForLove marry for love]] after [[spoiler: he just broke up with his mistress, Siena, in season 1]], but also because he has been holding an emotional wound of a traumatic past[[note]]he watched his mother became terminally depressed following his father's sudden tragic death due to a bee sting[[/note]], while Kate represses her eventual feelings for Anthony because she (initially) disliked him[[note]]she overheard about his wish to not marry for love and his overbearing wishes for a wife[[/note]] and [[IWantMyBelovedToBeHappy wants to make her younger sister, Edwina, happy]]. [[spoiler:They eventually can't fight their true feelings for each other, thus they end up marrying.]]

* ''Series/{{Moonlighting}}'': This was the whole premise of a romantic {{Dramedy}} series starring Creator/BruceWillis and Cybil Sheppard as private detectives. In the fifth season when they finally consummated their relationship; the tension was simply gone and it become yet another sitcom. Lampshaded in the series finale, a great example of the show's frequent BreakingTheFourthWall. The two detectives come back to the office to find it being dismantled by people working for ABC; an ABC network executive tells them that viewers had enjoyed watching them fall in love, but after they'd already fallen they lost interest. [[note]]In reality the downfall of ''Moonlighting'' had a lot of other causes as well. Mostly it was the result of tons of behind-the-scenes problems that plagued the show for the duration of its run, ranging from script and episode delays to a writer's strike that struck mid-season to the declining quality of scripts to (infamously combative) lead actors who simply didn't want to continue working on the show. Bruce Willis launched his film career with ''Franchise/DieHard'' between the third and fourth seasons and Cybil Sheppard, reportedly never pleased with the long working hours, wanted more time off to spend time with her growing family.[[/note]]

* ''Series/SportsNight'': Has it in spades between Dana and Casey. Then later between Dana and [[FoeYay Sam]].

* ''Series/{{Victorious}}'': Jade and Tori have a ridiculous amount, be it of the most extreme FoeYay-meets-LesYay variety, but harder to deny as the series wore on.

* ''Series/GossipGirl2021'': In contrast with [[BelligerentSexualTension the Max/Audrey relationship]], Aki and Max have mutual attraction as well but Aki's newfound bisexuality makes things more underlying. [[spoiler:Episode 6 implies the pair have sex in a threesome with her.]]

* ''Series/Daredevil2015'': Matt Murdock and Karen Page right from the start have some visible UST, but it's clear Matt's unwilling to act on it because he's hesitant about her finding out about his alter ego as the Devil of Hell's Kitchen. By season 2, they've loosened up enough that they finally have their first kiss and first date

*** Romana II in the 1979-1980 era, due to real life bleeding into the production as Tom Baker and Lalla Ward were dating (and married a few weeks after she left the series). It's been noted that you can tell when Tom and Lalla had had a fight (and they even broke up briefly at one point) by how the Doctor and Romana interact on screen.
