* CrossesTheLineTwice: A lot of the humor, especially in the manga. If you're not into BlackComedy, then this series isn't for you.
* EndingFatigue: The manga doesn't seem to know how to end. Once it finally did end in early 2015, it was a looong time coming.
* HoYay:
** Mostly involving Yuki, specially in the episodes centered around him.
** With all four bishonen in general, at least occasionally, though it's almost always PlayedForLaughs.
** One time, when Sunako was being harassed by Kyohei's fangirls and the guys told Kyohei to say something to stop it, he announced he was going out with Ranmaru. In a later chapter, when Kyohei was being haunted by the spirits of said fangirls, he actually kissed Ranmaru in his sleep. In both cases, the fangirls [[YaoiFangirl didn't seem to mind.]] Ranmaru, on the other hand...
** Kyohei clinging onto Takenaga in a very loving manner. He usually only does this when [[ClingyJealousGirl Noi]] is around, though.
* NarmCharm: This series is just ridiculous; the characters are always screaming, the conflicts that arise are driven solely by RuleOfFunny and/or RuleOfCool with no regard reality, the ways the characters solve the conflicts are ham-fisted at best, the [[OffModel animation is wonky]], and in the end, [[StatusQuoIsGod nothing is ever really accomplished.]] But you know what? It's ''fun.''
* NightmareFuel: Sunako is this to most people because she is a "creature of darkness" who likes creepy things.
* TearJerker:
** In the J-Drama, Kyohei bursting into heart-broken sobs right after [[spoiler: his mother has a breakdown, screams that she shouldn't have given birth to him, and his father forbids him to see her (to make matters worse, this is the scene right after Kyohei's mother seems to accept him again and has asked him to come home more often)]].
** Also this line from the last episode of the anime: "The best person for me has already passed away...." Poor Auntie!
