A stiff character learns and grows from unwanted interaction with annoying and eccentric people.

The focus character is a fairly stiff guy (rarely a gal), may be the OnlySaneMan, TheComicallySerious or a {{Jerkass}} of the "stick up his rear" type, and often comes across as an IneffectualLoner. He may not be content with his life, but it's stable, and he probably has a long-term plan for fixing what he thinks is wrong, if he can just get the right breaks. Instead, he is dragged into wacky hijinks by the other characters against his will, making a mess of his life. But implicitly or explicitly, the goal in the story is to [[MiseryBuildsCharacter make him a better person by putting him through "horrible" experiences]] - or at least ones he ''considers'' horrible, in order to show him the brighter side of things.

May involve a ManicPixieDreamGirl, but in most examples, it's an entire cast imposing on the stiff guy's time, money and patience. ThePowerOfFriendship is usually evoked by the end of the story. There may be a montage as the character remembers how things used to be, and how despite how much the other characters irritate them, they have made stiff guy a better person by getting him to take off his JadeColoredGlasses.

Contrast DefrostingIceQueen, an AlwaysFemale version, and UnsympatheticComedyProtagonist, who may have a similar personality and equally annoying cohorts, but does not have the CharacterDevelopment.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* ''Manga/RozenMaiden'': Jun is a {{hikikomori}} until Shinku forces him to be her "medium", interacting with her and the other crazy dolls and eventually humans brings him out of his shell.
* ''Manga/GashBell'': Kiyomaru, who was hiding out at home until Gash forced him to interact with people.
* ''Manga/MidoriNoHibi'': Seiji thinks that his problem is not being able to get a girlfriend, but that's actually just a symptom of his general inability to interact non-violently with others. Having to protect Midori and her secret, and deal with wacky people he can't just punch, brings out his better qualities.
* Explicit in ''Manga/HauntedJunction'': Hayato, who says IJustWantToBeNormal, but is constantly dragged into supernatural mayhem. In the final episode we learn that the school spirits have been tormenting him specifically to avert a BadFuture in which he lives a "normal life" but never emotionally connects with anyone including his future wife and child. Which seems to lead into a happy ending...except that said PreachersKid was made so miserable by the constant torment that he voluntarily participated in a plan to kill or imprison all the school spirits; and there's no indication that things are going to get better for him.
* The plot of ''Manga/HappyLesson'' kicks off when Chitose's teachers decide that what he really needs are five mothers running his life. (He discovers, much to everyone's surprise, that he does become a more well-adjusted person because of them.)
* ''Manga/SumomomoMomomo'': Koushi never wanted an ArrangedMarriage or to be surrounded by lunatic martial artists bent on killing/loving him. But after Momoko finally admits she knows he doesn't love her, Koushi acknowledges that his experiences have broken him out of his fear of confronting other people (even if he's still a physical coward.)
* The residents of ''Manga/MaisonIkkoku'' spend most of their time driving Yusaku Godai insane with their alcohol-induced insanity, but also end up somehow making him the man he needs to be for Kyoko, as well as get Kyoko to reflect on her feelings for him.
* The ''LightNovel/HaruhiSuzumiya'' works imply this is the case for Kyon, who became a much more outgoing and likable guy after exposure to the SOS Brigade. They ''invert'' it with Haruhi, who became a more sympathetic person by hanging out with [[LockedOutOfTheLoop apparently]] normal people.
* ''Manga/ArakawaUnderTheBridge'': Ko/Recruit starts the series as someone who sees all human interaction as a series of debt transactions, in which he must never remain the debtor. Being forced to live with the zany riverbank community allows him to learn to interact with other people on the basis of honest emotion, without being concerned about who "owes" who. Lampshaded when Recruit realizes he hasn't had an asthma attack (symptomatic of his fear of debt) in quite some time.
* ''LightNovel/{{Baccano}}'''s Firo Prochainezo outright admits this to himself in ''Alice in Jails''. Early Firo was cynical and occasionally downright vicious (as demonstrated by his "excessive self defense" against a mugger in his EstablishingCharacterMoment). Then [[FunPersonified Isaac and Miria]] came along...
* [[JustifiedTrope Justified example]]: [[{{Telepathy}} Haruka]] [[AllOfTheOtherReindeer Kotoura]] of ''Manga/KotouraSan'' has been carrying a JerkassFacade [[NeverBeHurtAgain to keep herself from being emotionally hurt]] by [[LeaveMeAlone being forever alone]], but [[{{Cloudcuckoolander}} Man]][[ChivalrousPervert abe]] and the [[TrueCompanions ESP club]] can see right through it and know how much [[HurtingHero she's actually hurting herself with it]]. If not for them, she would have been a BrokenBird for who knows how much longer or worse as [[spoiler: [[NotSoDifferent Detective Tsukino]]]] shows us in episodes 9 through 11 as a jealous, child-beating criminal.
* ''Manga/KagerouDays'': Implied to be the reason why Ene forces Shintaro to join the Mekakushi-Dan. Said friends include a {{Bokukko}}, a FriendToAllLivingThings, a ConsummateLiar, a fellow {{Hikikomori}}-turned gang member and [[CuteClumsyGirl his little sister]]. [[MagicalEye Oh, and they've all got super powers.]] Notably, [[InsufferableGenius Shintaro himself was already quite eccentric]]; his only problem being that he's a [[{{Hikikomori}} shut-in]], and it's doing nothing for his mental health.

[[folder:Literature]]
%%* The plot of ''The Truth About Forever'' by SarahDessen.
* Arthur Dent's utterly miserable struggles through a WorldGoneMad in ''Literature/TheHitchhikersGuideToTheGalaxy'' do improve his bravery and will to the point where he's able to prevent Trillian leaving a party with obvious jerk Thor (a reversal of when he failed to prevent Trillian leaving a party with obvious jerk Zaphod in the backstory), fend off his [[ButForMeItWasTuesday accidental nemesis]], and learn to fly. At a couple of points, he even tires of the simple life he repeatedly claims to long for and decides to go off travelling through space again. On the other hand, it does leave him a scared, frustrated and rather depressed wreck.
* ''[[Literature/AMagespower A Mage's Power]]'': ZigzaggedTrope. Aio, Eric's first friend in Tariatla, is certainly loony. His schoolfriends, Revas, Oito and Annala, are not loony in the least, but his guild friends are plenty loony. All of them work together to help him [[GrewASpine grow a spine.]]
[[/folder]]

[[folder:Film -- Animated]]
* ''Film/{{Shrek}}'' has a lot of this happen to him, with Donkey being the primary loony friend.
* ''WesternAnimation/{{Cars}}'', Lightning Mcqueen starts to like Radiator Springs after being around all of the crazy characters
[[/folder]]

[[folder:Film -- Live Action]]
* Tim from ''Film/DinnerForSchmucks'' after hanging around with Barry.
* Claude from ''Theatre/{{Hair}}'' epitomizes this trope.
* ''Film/TheFisherKing''. The "stiff guy" is a shock radio host, but he's still quite stiff. And the looney is...well...Robin Williams. As a crazy homeless guy. It's a surprisingly serious movie, but still, you can see where this is going.
* Subverted in ''Film/TheCableGuy'', where "Chip" at first seems like a quirky but fun guy who helps Steven learn to loosen up and live a little, but Steven soon discovers that his new buddy is rather creepy, manipulative and even dangerous. Then he tries to end his friendship with "Chip," and things get even darker.
* Played straight in ''Film/GuardiansOfTheGalaxy'', where exposure first to Peter Quill and then to each other makes Gamora, Drax and Rocket all loosen up.
[[/folder]]

[[folder:Live Action Television]]
* Jeff Winger in ''Series/{{Community}}'' grows (slowly and with much backsliding) from {{Jerkass}} to JerkWithAHeartOfGold when forced to interact with his unwanted study group. See especially the episode "Paradigms of Human Memory."
** Deconstructed in "Studies of Advanced Movement", when Annie -- a similarly stuffy and uptight character (while hardly the OnlySaneMan) -- is moving in with Troy and Abed, the show's primary source of wacky hijinks, and is advised to be flexible with them. After an increasingly trying and stressful first day of putting up with their antics, however, she snaps and delivers an angry lecture about how unfair it is that she always has to be the one to adapt to their personality quirks while they seem to show no intention of attempting to accommodate her.
* This is the basic plot of ''ProducingNobuta''.
* In ''Series/KamenRiderFourze'', Kengo starts out as an antisocial prick. By his eighteenth birthday party, hanging out with the quirky Kamen Rider Club has made him mellow out considerably--he even credits them with this transformation. Every other character save for Gentarou and Yuuki has gone through a similar, if quicker and less drastic, transformation.
-->'''Tomoko:''' "I think you've become more human."
-->'''Kengo:''' "With such egotistical club members around me, it's only natural to change. But...being more human probably isn't so bad."
* ''Series/TheXFiles'': AgentScully, who is friend [[TheyDo (and more)]] with fringe theorist AgentMulder. A rare case where the person improved is a woman.
[[/folder]]

[[folder:Webcomics]]
* Susan in ''Webcomic/ElGoonishShive'', thanks to her friendships with the rest of the main characters, but ''especially'' with [[ChivalrousPervert Tedd]], has grown from a StrawFeminist DeadpanSnarker to a nicer DefrostingIceQueen.
[[/folder]]

[[folder:Web Original]]
* [[OnlySaneMan Agent Washington]] has a massive case of this, if you can call [[RedVsBlue the Reds and Blues]] [[VitriolicBestBuds 'friends'.]]. It's notable that Agent Carolina was a lot warmer around her more eccentric Project Freelancer teammates, specifically [[AcePilot 479er]], [[MasterOfUnlocking York]] and [[SkilledButNaive the younger Agent Washington]].
[[/folder]]

[[folder:Video Games]]
* Squall in ''VideoGame/FinalFantasyVIII'' is a classic example. He's a very down to earth [=SeeD=] member who likes to focus on the task at hand. Unfortunately for him he's forced into dancing at a graduation ball by a ManicPixieDreamGirl. And things just keep getting stranger from there.
** This is brought up again in ''VideoGame/DissidiaFinalFantasy'', where he keeps running into [[FunPersonified Bartz]] and [[{{Keet}} Zidane]] and keeps getting caught up in their own quest to find the crystals.
[[/folder]]

[[folder:Western Animation]]
* Twilight Sparkle in the premier of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' is made a better pony of sorts when forced to make new friends, some of whom are definitely bizarre. Given the Aesop setup of the show, and some visible CharacterDevelopment, all six ponies trade this trope around with each other.
* For fifty-two straight episodes of ''WesternAnimation/AvatarTheLastAirbender''(out of ''sixty-one''), Zuko is a moody jerk. Being forced into a "life-changing field-trip" with [[ManicPixieDreamGirl Manic Pixie Dream Boy]] Aang calms and brightens him enough to interact with people without shouting over the course of '''a single episode.''' Much of his issues are recovering from the trauma of breaking with his insane father and sister, leading to an identity crisis.
