* FollowTheLeader: Spawned a bunch of low-budget films for Japanese musicians, most notably 2004's ''Film/{{Oresama}}''.
* HoYay: Sho and Kei are very close. To the point that Kei suggests they should "Spend more time apart."
* SpecialEffectFailure: When they burn at the end.
** Though, to be fair, the only person we actually see burning in the entire movie is Luka. Way before the end.
* TearJerker: [[spoiler: Toshi's death]] and many moments after the nine-year timeskip, including [[spoiler: Kei's prison scene where he calmly asks to be thrown into the sunlight, Sho's "death" at the hands of Son, Yi-che's inability to recognise that her husband was not Kei but Sho after she got the tumor, Sho begging Kei to come save him because he had no idea what to do anymore, and several more.]]
