-->'''Kusakabe, after trying to run out under a rainstorm''': [[CaptainObvious I got wet]]!!!
-->'''Sajou, applauding''': Oh, well done.

->'''Hashimoto:''' "I lost the chance to find out what my true feelings were back then, so I guess...that's something I regret."

->'''Hashimoto:''' "Hara-Sensei. It's Hikaru Kusakabe isn't it?"
->'''Hara-sen:''' [SpitTake] "NO WAY IN HELLLL!!!"

* {{Foreshadowing}}: Sajou's dream after passing out in the train station involves Kusakabe cutting the yellow ribbon between them (representing their relationship) but promising to re-tie it later after they sort things out. This becomes the plot of ''Blanc'' where both characters were going through a low point in their lives, Sajou requests a break from their relationship but Kusakabe misinterpreted as ending it and [[ReturningTheWeddingRing returns the former's ring]], spent several chapters regretting and missing one another before finally making up and marrying.

* SharePhrase: Kusakabe's hair being described as "fluffy" by various people in their inner monologue or thoughts

* ThemeNaming: "Hikaru" and "Rihito" ("Licht") both mean "light" in Japanese and German, respectively.

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

* SickeningSweethearts: In spite of Sajou and Kusakabe not displaying much public affection, the off-handed comments their relationship is enough to make people envious and/or embarrassed, especially for Sajou's friends.
* SingleTargetSexuality: Kusakabe didn't have any romantic interest for anyone until Sajou, even calling him his FirstLove and iin one bonus chapter when rifling through his sister's Yaoi manga, he specifically picks one that has a boy on the cover with similar glasses, haircut and body type like Sajou. Tani even thought he was the type of guy who couldn't love anyone back which could mean Sajou was more than just his ClosetKey.

* TeacherStudentRomance: The other two official couples with Hara-sen and Satoshi as the teachers to their students Sarano and Hibiki respectively though it's subverted as they only started dating after graduation.

* YaoiFangirl: Kusakabe's older sister secretly is one and has several containers worth of Boys Love manga all carefully organized underneath her bed. He tried using the manga for sex research but found it confusing and ridiculous then got in deep trouble once she found out. During Sajou and Kusakabe's wedding, she was blushing so hard despite her stoic nature as it was a dream come true.

* SingleTargetSexuality: Kusakabe didn't have any romantic interest for anyone until Sajou, even calling him his FirstLove in one bonus chapter and in another when rifling through his sister's Yaoi manga, he specifically picks one that has a boy on the cover with similar glasses, haircut and body type like Sajou. Tani even thought he was the type of guy who couldn't love anyone back which could mean Sajou was more than just his ClosetKey.

* AdaptedOut: While the movie is incredibly faithful to the first volume it was based on, "His First", the third chapter between "Autumn" and " A Complex Fool and a Simple Fool" which Hara-Sen recounts his first meeting with Sajou in first year, was cut out entirely. This left him with significantly less screen time and without the reason why he fell in love with Sajou in the first place.

* OppositesAttract: Basically the premise. Sajou is straight-laced, studious and emotionally reserved while Kusakabe is laid-back, seemingly directionless and very honest about his feelings, yet they are madly in love with each other.

* BittersweetEnding: ''Blanc'' ends with the Sajou and Kusakabe reconciling and HappilyMarried with a wedding ceremony attended by 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 Satou was gay]].

* 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.

* {{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 more reserved Sajou's.
* 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 Kasukabe 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. 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 he refuses to have sex with him until he turned twenty).

In an all-boys high school, a class is preparing for an upcoming chorus festival. As the boys sing, Hikaru Kusakabe notices that one of his classmates, Rihito Sajou, is not making any noise. Hikaru Kusakabe is a sleepy-eyed, carefree slacker who plays guitar in a band, Sajou is a straight-laced and serious honor student who got perfect scores on every subject on his entrance exam. Kusabake concludes that the two come from completely different worlds, so there's no reason the two would have any reason to talk, and as such, he'll never know why Sajou doesn't sing.
