Looking for something similar to "Chiaraijima Kanako wa naze ○○ suru no ka?"

[Hejti]

Can anyone recommend sth similar? Like boy living with an adult relative or just and adult woman or just landlady with some comedy, romance and ecchi if possible.

Would like to avoid shota unless it is a really nice manga.
