History Manga / ShishunkiBitterChange

* OreOnna: Yuuta slips into it when he's feeling especially anxious.

* BittersweetEnding: The manga ends this way, averting the DownerEnding below for a happier conclusion. [[spoiler:Yuuta and Yui finally switch back to their original bodies after 8 years, but with Yuuta in critical condition as a result. This causes Yui to finally acknowledge the good times they had together and admit her love for Yuuta, praying for them to swap bodies again if it means he can be saved, which gets answered sometime off-panel. Yuuta and Yui start dating and fully accept their circumstances, as signified by them calling themselves by the other's name, even in private (Though Yui still calls Yuuta her boyfriend), though in the process saying goodbyes to their old lives in the process. The epilogue shows they have gotten married and have two children, and they go out of their way to prevent them from going through what they experienced.]]

* BabiesEverAfter: [[spoiler:Both ''Change'' and ''Bitter Change'' end with an adult Yuuta (still stuck in Yui's body) becoming a mother to two kids. The father in the original comic is unknown, while the manga does show that it is Yui (who is similarly still in Yuuta's body).]]

* BabiesEverAfter: Both ''Change'' and ''Bitter Change'' end with Yui('s physical body) having children. [[spoiler:We don't know who the father is in the web version, but in the manga's epilogue it's very obvious they're hers and Yuuta's]].

* FirstPeriodPanic: Yuuta recieves one of these when he experiences his first one in Yui's body.

** While happier, the end of ''Bitter Change'' initially leaves it up in the air whether or not [[spoiler:Yui and Yuuta actually switched back. "Yui" refers to Yuuta's body as "Yuuta", implying that they're in their proper bodies, but "Yui" is uncharacteristically protective of "Yuuta", Kazuma laughs off the idea of liking "Yui", and "Yuuta" teases "Yui" by calling her a dishonest ''boyfriend'', implying the switch Yui wished for happened in Chapter 63. The final volume's extra comic gives a more concrete answer; "Yuuta", while looking at a sleeping "Yui", comments that people never get to look at ''their own face'' in full, showing that they indeed switched for good and they [[BecomingTheMask now refer to themselves as each other's names.]] Further released Twitter extras remove all ambiguity that they did in fact remain switched as they had the past couple years: in one, Kazuma refers to Ex-Yui-Now-Yuuta as "Yui" while talking to Ex-Yuuta-Now-Yui, suggesting privately they still (at least occassionally) use their birth names. In another, Ex-Yuuta-Now-Yui verbatim thinks "Yui would be furious if she found out." due to having gained a little weight.]]

* {{Transgender}}: Yui and Yuuta end up being the opposite sex, physically, but both of them still identify with their original gender. This leads to a lot of discomfort and dysphoria for the pair.

** Briefly, Yuuta's younger brother figures out that his brother now is not his original brother but vows to keep it a secret. As he grows older however, [[RealityEnsues Yuuta's brother starts to believe Yui's personality is how his brother has always been and forgets about the swap entirely.]] Yuuta's brother though does the remember the promise he made regarding his bet with "Yuuta" as shown when his brother ended up in critical condition, even he if doesn't remember the circumstances leading to such a bet.

The manga was based off of the four part web manga ''Change'', also made by Masayoshi, which was released throughout 2012-2013. It was later uploaded onto Masayoshi's Pixiv account as a 21-part series. A WhatIf manga following Yui and Yuuta if they hadn't switched, ''Change, Shitenai'', was sold as two independent doujin mangas from 2013 to 2015 before both volumes were compiled online.

The manga was based off of the four part web manga ''Change'', also made by Masayoshi, which was released throughout 2008-2012. It was later compiled into four parts on a separate website.

''Shishunki Bitter Change'' is a GenderBender manga that starts off with a fairly typical premise: boy falls out of tree onto girl, they switch bodies. What differentiates it from other, similar manga, is that the situation is much more long-term. They go years without switching back, and Yuuta and Yui have to settle in to their new lives in each other's homes.

* {{Transgender}}: Yui and Yuuta end up being the opposite sex, physically. but both of them still identify with their original gender. This leads to a lot of discomfort and dysphoria for the pair.

* WhatTheHellHero: Yuuta calls Yui out on her judgemental attitude when she assumes Tachibana will try to take advantage of him just due to looking like a delinquent.

* FirstLawOfGenderBending: The main characters undergo a mixed-sex body swap (thus a straight and inverted example) and go years without any sign of reversing it. [[spoiler:Near the end of the series, they do switch back, but Yuuta starts dying seemingly as a result, causing Yui to wish they would change back again. Yuuta's body recovers, and is [[AmbiguousEnding implied though not clearly shown]] that each went back to the other's body and accepted them as their own from then on.]]

* CelibateHero: Yuuta displays no romantic or sexual interest in anyone or anything, though that could just be a prolonged case of immaturity. [[spoiler: Not anymore as of recent chapters. Yuuta is showing increasingly jealous reactions towards Yui hanging out with other boys, although he does not understand exactly why yet.]]

* DownerEnding: Not the manga, but the original webcomic ended on an incredibly bleak note. [[spoiler: Yuuta, in Yui's body, was distracted by the realization he had a crush on Tachibana and failed to notice Yui (in Yuuta's body)'s deteriorating mental state. There's a time skip and a scene which implies Yui killed herself and Yuuta ultimately continues living in her body, even getting married and having a child, while lamenting to Kazuma that he felt like he could have done more if he'd only been mature enough to understand Yui at the time.]]

* FirstLawOfGenderBending: No signs that they are going to be able to change back anytime soon, even after [[spoiler:6 years.]]
** [[spoiler:Averted at the last moment in Chapter 62. See the Wham Episode entry.]] And then double subverted in Chapter 64, as [[spoiler:Yui herself prays to God to switch them back]].
* FreakyFridayFlip: without the flip back usually found in such plots.
* FriendlessBackground: Yuuta tends to gravitate towards these types of people and entering their lives, from Yui to Koizumi.

* GenderBender: The premise of the comic. Notable in that the situation has no easy fix, and Yuuta and Yui are stuck as each other for the long term.

The ramifications of spending many years as someone else are shown, as the series follows Yuuta and Yui all the way through high school. It's prime example of GenderBenderAngst where there are no wacky hijinks associated with the swap, and the change does take its emotional toll. Still, over time, the two settle into their new roles, but they wonder if they will ever return to their old lives, and after so much time, are their lives even their own anymore?

The ramifications of spending many years as someone else are shown, as the series follows Yuuta and Yui all the way through high school. Thus, it can be considered something of a {{Deconstruction}} of the GenderBender genre in that there are no wacky hijinks associated with the swap, and the change does take its emotional toll. Still, over time, the two settle into their new roles, but they wonder if they will ever return to their old lives, and after so much time, are their lives even their own anymore?

* SecondLawOfGenderBending: Averted. Much of the series consists of either Yuuta or Yui grousing about the inconveniences of life as the other gender (mostly Yuuta). While they do learn to adjust out of necessity, they never really seem to enjoy it.

''Shishunki Bitter Change'' is a GenderBender manga that starts off with a fairly typical premise: boy falls out of tree onto girl, they switch bodies. What differentiates it from other, similar manga, is that the situation ends up becoming permanent. There's no quick fix or easy solution, and Yuuta and Yui have to settle in to their new lives in each other's homes.
