* HopeSpot: [[spoiler: After Ryuu tells Ikki about Toshimitsu's death, a new chapter starts with Toshimitsu waking up from a bad dream which kinda leads us to believe that Ryuu got his death wrong. It turns out to be a sort of flashback that no one is having since we then witness his last drug trip, his last call to Ryuu, and his suicide.]]

* MeetCute: Ryuu leaves a really bad first impression on Ikki, which leads to Ikki punching him.
* PlayboyBunny: Mostly appears in Toshimitsu's hallucinations.
* [[spoiler: PosthumousCharacter: Toshimitsu has been dead for a few years in the start of the story, and while we only get to know him through flashbacks, he's arguably the most developed character in the manga.]]
* SecondLove: Ryuu and Ikki might be this for eachother.
* {{Shotacon}}: The mangaka doesn't give out an age when Ryuu stared sleeping with his cousin, but we can guess it was a case of this since Ryuu was definitively not a high school student.
