* When the inappropriate picture of Shinji is posted on the main computer at school. Everyone had a different reaction. Takuya states that this is the best thing that has ever happened to him. [[AllWomenareLustful The girls are having their own fantasy.]] ''Atsuki'' writes in his profile about Shinji that it was amusing and how ''he deserved it.'' Akira? He missed it and will never know what was so funny.
* The episode where Atsuki comes into Ryo's bookstore at night by Ryo's request. After going in the back room, Ryo dumps a bunch of books on his lap...and it keeps on piling to the point that it might as well cover the whole screen. [[NotsoStoic Atsuki's face is priceless]] and [[SelectiveObliviousness Ryo doesn't even realize that there's a problem.]] [[http://24.media.tumblr.com/tumblr_mdvmtz2q4H1qdujodo6_400.png It has to be seen to believe it.]]
* During class in one episode where Aoi is already pissed off at Shinji for something he did. She punishes the whole class by having a surprise test. Mika's reaction was suspected but Akira who is known to be asleep in every class (according to Atsuki and judging from the fact he never participates in group conversations) [[InstantWakingSkills suddenly wakes up]] and he's like, "ARE YOU SERIOUS?" [[EpicFail You can pretty much tell he failed that test with Mika.]]
* In the normal ending [[spoiler: if you fail to save Hibiki]], Akira tackles Atsuki down on the ground because he thought he was a suspicious person. Upon seeing his mistake, Akira tries to make up to Atsuki by treating him to free cake (one that he personally made) at his place. Cue the {{ship tease}}.
* Ryo (indirectly) calling Rui stupid and she doesn't realize it until after he leaves the room in episode 1.
* Akira's remembering the first time he met Rui and Mika recalling how they sent him to the hospital on the first day.
* Mika beating up Kyosuke after he brushed her off about her warning. [[spoiler: It becomes HarsherInHindsight when you realize that Mika's warning about him getting killed actually should have been taken to heart considering what happens to him later.]]
