* AudienceAlienatingPremise: Although this title does not actually contain any incest or pedophilia, his plot "the young guy develops a romantic attraction for one of his nieces, for whom he also [[ParentalAbandonment personifies the figure of their father]]" will naturally cause dislike among part of the audience.
* FunnyAneurysmMoment: in episode 10 of the anime, Nimura invites Miu out on a date. The same thing happens in the Shoujo manga, [[spoiler:except Miu's classmates have spotted them, and is now planning to use that information to get Miu in trouble.]]
* {{Narm}}: The family ties between the heroes are rather complicated and difficult to explain to outsiders. Just imagine that [[spoiler: Hina is the niece of Yuuta and the younger sister of his wife Sora, despite the fact that he and Sora are not related to each other.]]
* MexicansLoveSpeedyGonzales: Miu is very popular in Russian fandom, more than any other of the characters for quite obvious reasons, despite the fact that she is depicted as a typical foreigner girl in anime.
* StrangledByTheRedString: Anime falls into this, as the TV series actually ends before the official couple appears, and OVA after it.
* WTHCastingAgency: Sumire Uesaka is assigned to voice the main character, not her half-russian younger sister, despite the fact that Sumire professionally speaks russian and studied Russia at the university.
