* {{Adorkable}}: Mao is a dying fan of historical dramas, which she used to watch with her dad during their better times together.

* PerpetualFrowner: Daichi is certainly not a smiling cookie. He was born miffed and always sports a scowl.

* ShesAllGrownUp: Underneath his deadpan delivery when he met Mao again in Hiro's house, Daichi was taken aback when he saw her again, not a bratty child like before, but a woman altogether.

* MasterOfTheMixedMessage: Hiro is terrible at setting things straight with Mao, which sends her to unnecessary tangents that she could avoid if he were more direct with her.

* RavenHairIvorySkin: Mao has beautiful long black hair and very nice skin. Part of the reason she gets confessed to so often.

* SoProudOfYou: Daiki summarizes Mao, explaining why [[he likes her so much]]:

Always did her best to find her way.\\

Always\\
Always"\\

* {{Foreshadowing}}: During the fireworks at the summer festival, Daili catches a glimpse of Hina in the crowd and starts chasing after her while dragging Mao from her hand.

* MyGreatestFailure: The main reason why Hina refuses to live with Hiro and Daichi is because [[spoiler:she rationalized that [[ItsAllMyFault she killed her mom and dad]] with her capriciousness, so [[HeroicSelfDeprecation she doesn't deserve to live a happy life with her brothers]]. Mao's dad dispels this notion on her, finally accepting to live with them]].

* SliceOfLife: Most of the manga consists of the household interactions between Mao and Hiro, and later Daichi.

* WriteWhatYouKnow: Mao's InUniverse cell phone novel "House of the Sun" (under the penname "Kuukai") is basically her living with Hiro, but changing their names (e.g. Mao to Kaoru, Hiro to Takeshi). Hiro doesn't realize this, mistakes the kanji for "Kuukai" as "Sorami," and thinks the novel is by his co-worker Sugimoto because she is rumored to writes novels and he feels as though "Kaoru" is similar to Sugimoto; in reality, Sugimoto is merely a fan of Mao's novel.

* MyGreatestFailure: The main reason why Hina refuses to live with Hiro and Daichi is because [[spoiler:she rationalized that she killed her mom and dad with her capriciousness, so [[HeroicSelfDeprecation she doesn't deserve to live a happy life with her brothers]].
