History Manga / Doukyusei

* BlanketFort: Kusakabe makes one in "Home", as it's cold in their new apartment and they haven't yet unpacked any furniture.

* CerebusSyndrome: ''Doukyusei'' didn't had much tension so its sequel ''Sotsugyousei'' upped the angst by having Sajou's mother diagnosed with terminal cancer and the couple's fear of separation because of Sajou attending university at Kyoto while Kusakabe wants to stay in Tokyo. ''Blanc'' then intensifies it when Sajou interprets Kusakabe saying they don't have to rush getting married as him forgetting the promise they made in ''Sotsugyousei'', and asks to take a break from their relationship, which Kusakabe in turn misinterprets as Sajou ''wanting to end it''. If that's not enough, Sajou's mother is back in the hospital after her cancer becomes severe [[spoiler:and tragically dies from it]].

* * WideEyesAndShrunkenIrises: How they portray people who are especially shocked that they are stunned speechless.

* {{Gayngst}}: Sajou was more uncomfortable with his sexuality since unlike Kusakabe, Sajou always knew he was attracted to the same sex since young but hides it in fear of his parents' disapproval as opposed to [[ClosetKey experiencing romantic interest for the first time]] and not being afraid to act on it (He does get better over time the more time he spends with Kusakabe). It's noted Kusakabe was the one to initiate the kissing in the first volume until the last chapter.

** The bonus chapter "The Night Before" expands on the events after the kiss. Sajou rushes home with his heart seriously pounding hard from thinking back on it while Kusakabe reflects in the bath on why he kissed Sajou before [[LoveEpiphany realising his awakened feelings for him]] [[[[ClosetKey that he never had before with any of the girls he previously dated]].
* FirstLove: Sajou is this for Kusakabe.

* InsultOfEndearment: Sajou calls Kusakabe "Idiot"[[note]]Baka in Japanese[[/note]] whenever the latter says something romantic that embarrassed him.

* BittersweetEnding: ''Blanc'' ends with the Sajou and Kusakabe reconciling and HappilyMarried with a wedding ceremony attended by their friends, family and about every significant character in the series. However, it doesn't change the fact that [[spoiler:the former's mother succumb to her cancer as well as being unable to fix his rocky relationship with his father, especially after he found out Sajou was gay. (However, they're starting to repair their relationship by the time Futarigurashi rolls around)]].

''Blanc'' then intensifies it when Sajou interprets Kusakabe saying they don't have to rush getting married as him forgetting the promise they made in ''Sotsugyousei'', and asks to take a break from their relationship, which Kusakabe in turn misinterprints as ''Sajou'' wanting to end it. If that's not enough, Sajou's mother is back in the hospital after her cancer becomes severe [[spoiler:and tragically dies from it]].

** Kusakabe gives Hara an insulting one in the form of "Chin Pubes" in the official English translation. ("Hige" in Japanese.)

* MayDecemberRomance: Hara-Sen had initially wanted to be in one with Sajou but thought it would be wise to wait until graduation to ask him out ([[HopelessSuitor Too bad Kusakabe came into the picture before he even had the chance]]). Years later, Hara-Sen is 37 years old and single in "Sora to Hara". Still reeling from his former crush, he kisses a guy in a nightclub who is later revealed to be Sorano, one of his first-year students and 15 years of age. Unsurprisingly, Hara was shocked to realize the ''twenty-two'' year difference between them but over the course of the manga, Sorano became his SecondLove and agreed to date him after his graduation (though Hara refuses to have sex with him until he turned twenty).

* MeetTheInLaws: Chapter 10 of ''Blanc'' is pretty much dedicated to this.

* ''Occupation to Beloved''

* FirstNameBasis: Starting from ''Occupation to Beloved'', Kusakabe and Sajou decided to call each other Hikaru and Rihito since they would eventually share a last name after marrying.

* CerebusSyndrome: ''Doukyusei'' didn't had much tension so its sequel ''Sotsugyousei'' upped the angst by having Sajou's mother diagnosed with terminal cancer and the couple's fear of separation because of Sajou attending university at Kyoto while Kusakabe wants to stay in Tokyo.

If that's not enough, Sajou's mother is back in the hospital after her cancer becomes severe [[spoiler:and tragically dies from it]].

* RageBreakingPoint: After holding in his emotions from breaking up with Kusakabe ''and'' dealing with the grief of his mother's death (not to mention his lifelong fear of homophobia), what finally sends Sajou over the edge is his father's violent and homophobic response to his coming out, to the point where Kusakabe has to physically restrain Sajou. It gets uglier when his father switches targets to insult the love of his life.

* HighSchoolSweethearts: Sajou and Kusakabe began dating during middle school which continues well after graduation and into Sajou's university years before finally marrying and living together. While not showing much affection in public, their relationship is very lovey-dovey and intimate in private.

However, it doesn't change the fact that [[spoiler:the former's mother succumb to her cancer as well as being unable to fix his rocky relationship with his father, especially after he found out Sajou was gay]].

* Retcon: In a timeline of Kusakabe's life first released in 2010, it's stated his parents were a ChildhoodFriendRomance. This was eventually changed to a MayDecemberRomance with them having met at their place of work by the time ''blanc'' came out 10 years later.

* BrutalHonesty: Kusukabe isn't afraid to express his feelings for Satou and thoughts about getting married.

* {{Irony}}: Considering Sajou was his FirstLove but was taken by Kasukabe, which he considered his ([[HopelessSuitor one-sided]]) romantic rival, Hara-sen's SecondLove turns out to be Sorano whose cheerful, free-spirited personality is more like Kasukabe's than the reserved Sajou's.
