Ubuna 27-sai to Muku na 11-sai

Natsuki Jougyoji is a hard-working office lady who is dedicated to her job... but she can be inflexible and hard to get along with. Kaya Kozakura is a cheerful and positive child who always looks for the good in people. The two end up living together by chance…!? This is an age-difference comedy, living under one roof!
