Ooya-san wa Shishunki!

The middle school girl waiting in my new 1 room apartment(with no bath) is my landlord!? Plus, the beautiful next door neighbor raises my anticipation for the new chapter in my life.

I'm going to learn how to cook with the very cute Chie-chan wearing her aprons over her school uniform and the beautiful next door neighbor, Reiko-san, in the tiny 1 room kitchen. Isn't this the pinnacle of my life!?

Chie-chan is frightened when she feels someone is following her. Reiko-san can keep an eye on her during the afternoon, but since she has to work at night, Chie-chan is coming to spend a night at my place.

Coming home from work, I smell curry from my room!? I envision us being a domestic couple or a newlywed as Chie-chan greets me at the door, but she's more like a mom!?

Chie-chan goes straight home after school, so she doesn't belong in any afterschool club activities. Maeda and Reiko want her to enjoy her school life. Feeling their passion, Chie-chan finds the courage to take the first step…

Reiko accepted Chie-chan's request to make a "cute bento," but she rarely cooks. She somehow finished making a kyaraben, but the end result is...

Chie was able to make friends thanks to Reiko's kyaraben and even made a cooking club. With the free ingredients provided by the local grocery store, they begin making pork soup on the 1st day...

Maeda goes to public bath along with Chie-chan and Reiko. \r\nThe bath is filled with old men even though it just opened. It seems they are there for Chie-chan. \r\nThey are able to hear Chie-chan and Reiko's conversation next door if they listen carefully...

Chie is enjoying looking at grocery ads during recess. The worried classmates watch her and are surprised when they realize something... The mysterious Chie becomes the talk of the class.

Reiko runs into Mayu and Yuki who came over to study with Chie and notices something unusual with Yuki's body. Yuki, who is still developing, is not wearing the correct size bra. Chie and Mayu watch indifferently as the two share their pain of having a large chest.

Maeda and Reiko take Chie clothes shopping since she wears her school uniform every day. The two enjoy watching Chie try out different clothes like a model, but Chie is interested in something else...

It's the summer festival. Wearing a yukata, Chie meets up with her friends. Maeda is tagging along as a bodyguard. Protecting the girls from the crowd, Maeda turns into an event security. Maeda loses the girls, but Chie comes calling...
