* In the ''Manga/KimagureOrangeRoad'' movie, one phrase is enough to make you cry. ''"Goodbye, Hikaru-chan"''.
* In the manga, Hikaru starts to clue in on the fact that Kosuke is gradually making up his mind towards Madoka and tries to call him to talk to him about the matter. He picks up the phone and, before Hikaru can say anything, asks: "Is this Madoka?" (Madoka was, at the moment, literally running away from the problem because she'd realized that she had fallen for Kosuke.) The heartbreak that Hikaru suffers in this moment is ''excruciating''.
