History NightmareFuel / HisAndHerCircumstances

* Arima's dark side. Any time that he comes onto the screen, you just know Arima is seconds away from shattering. This is made worse because to the outside world, [[StepfordSmiler he appears to be a put together, genius]] with his only match being Yukino, his girlfriend. It's scary to slowly see his thoughts morph from wanting to be with Yukino, to wanting to isolate her from everyone and keep her just for himself. His fighting with these thoughts proves that Arima is a good guy, but him imagining tying Yukino in chains does not bode well for their relationship. This is a rare case of StalkerWithACrush in which not only is the stalker in a committed relationship with his crush, but he is also portrayed as so sympathetic that you just want to save him from himself.
** The worst has to be the end of Chapter 42 right after Yukino decides that she wants her world to be bigger than just her and Arima. The realization that he cannot bind her to him makes the dark side that Arima was always trying to hide come out. [[http://www.mangaeden.com/en-manga/kare-kano/42/40/ And it is frightening.]]
** He also stabs himself in the freaking hand in Chapter 72, after [[spoiler: he believes that he has raped her]], in order to atone for his mistake. Made worse by how ''that'' scene comes out: [[spoiler: Arima is still in his BreakHerHeartToSaveHer phase after [[TraumaInducedAmnesia recovering his memories]], and she has given him a CooldownHug. Then Arima gives Yukino a ForcefulKiss and pins her to the floor, and [[RapeDiscretionShot the scene pans to her disheveled hair and spread school things as she tells Arima to wait.]] This is followed by an odd scene where Yukino sees a small Arima in the middle of a thorny path and he keeps explaining to her how Ryouko abused him one last time before she abandoned him and he was taken in by his uncle and aunt]]. And last but not least, as [[spoiler: Yukino lays on the floor [[SexyShirtSwitch covered by Arima's school jacket]] and hugs it in tears]], [[spoiler: Arima mentally berates himself at home for "forcing his feelings on her"... and THEN goes the ImpaledPalm way.]] It's both terrifying and [[TearJerker heartwretching]]: how really fucking '''broken''' you must be to do that?!

* The fact that the very first meal Arima had with his aunt and uncle served as the ''very first meal he had ever had'', having basically survived up until than on table scraps, stale bread and whatever cheap crap his mother left in the house that he could get to. And said mother would torment her starving child by eating in front of him while refusing to share, even flying into a rage when a lady offered her child a free ice cream. That is how horrible a mother Ryouko is.

** Especially Reiji's horror once he notices that Soichiro's crying in the background and he doesn't even know the address to save him really hits own straight into AdultFear territory.
** And seeing Soichiro's broken little body in the snow from ''Reiji's'' perspective [[AdultFear was pretty horrifying too.]] No wonder he immediately handed the poor kid to his brother and sister-in-law [[spoiler: and years later wants to '''murder''' Ryoko.]]
