Provides examples of the following tropes:

- All Women Are Lustful: Pretty much every female resident of Sunohara-sou is perverted to some degree, and most of them exhibit this by seeing Aki as a cute boy they can treat as a toy.
- Nana and Yuri are the worst offenders who have been physical with Aki a fair few times, with Nana even trying to get dirty thoughts into Aki's head when she presents herself.
- This also extends to Nana's friends, with Nana using Aki as a bribe to make them do their homework in exchange for them playing with his body however they like for a certain period of time.
- Then Aki's older sister, Matsuri, takes it the furtherest of all, seemingly wanting to fetishize Aki as a little sister.
- Animal-Eared Headband: Yuzu has one of the most unusual ones ever seen, wearing a plush chicklet-topped hair loop. She does so due to her Height Angst in a bid to look taller.

- Bland-Name Product: A Google knockoff appears as "Gaagle".
- Brother–Sister Incest: Matsuri Shiina displays very obvious attraction towards Aki, sneaking into his room, climbing onto his bed, and asking him to undress. The weird-er part is she seems to think of him as a little sister.

- "Dinner, Bath, or Sex" Offer: Yuzu once describes to Aki the kind of wife she wants to be and has a daydream where she welcomes home her husband with this exact phrase. However after noticing Aki fidgeting she adds "Or maybe you can eat my bath scrubbers instead!" while throwing them at Aki's head.
- Ear Cleaning: Ayaka is exceptionally skilled at this, having done this for Nana many times prior to the series.

- Everyone Calls Him "Barkeep": Aki always refers to Ayaka as "Kanrinin-san"note and Yuzu as Kaichounote .

- Yuzu has the height and A-Cup Angst variety, being extremely jealous of the enormous busts on the other girls she lives with.

- Matsuri who takes it to Clingy Jealous Girl levels, not wanting to share Aki with anyone else, especially Ayaka.
- Harem Genre: Aki is The One Guy in a lodging house full of girls, with many of them finding him cute and after his attention.
- Heroic Sacrifice: Played for Laughs when the Caretaker gets drunk and starts 'attacking' everyone. Sumire volunteers to hold her off while Yuri hides Aki, but both Sumire and Yuri get dragged off and tackled by Ayaka.
- Lap Pillow:
- Ayaka loves giving these and has done so for most of the Sunoharu residents, especially Aki. By her own admission Yuri is the only one who hasn't experienced yet to which she's been practicing for the day she finally does so.
- One time Yuzu insists on it in a bid to act as Aki's onee-chan.
- Like Brother and Sister:
- Invoked with Aki and the other girls of Sunoharu, especially Ayaka and Sumire who openly have declared themselves Aki's onee-chan.
- Yuzu actually fits the bill to Aki best of all, displaying something akin to a Sibling Rivalry with her tsundere moments, but also the one she's most likely to turn to for sensitive topics like her body image. The two actually hold each other tightly when they both become terrified.
