Yuuta Segawa is a university freshman who was looked after by his older sister, Yuri, but decided to live alone when Yuri got married.
Yuuta is starting college as a freshman in Tama University. He wants his sister to understand that he can take care of himself; he has a part-time job and is able to sustain his home.
Yuuta starts his school life surrounded by intriguing characters such as Raika Oda, a second year student of Tama University School of Literature. She is a very good cook and is the only female member in the Street Observation Research Society.
Meanwhile, at Yuri’s place, something is going on, she and her three daughters are preparing a surprise for their father. Yuri is really happy with her life, and wants Yuuta to understand and become part of her family. But Yuuta feels that he’d bother them with his presence.
Anyway, Yuuta is more concerned about school, one day; he found Raika sit next to him. The next he notices, is that he already has a crush on her. So he decides to join the Street Observation Research Society to spend more time with her.
One day, Yuri comes to Yuuta’s and implores that he visits them at her home on Sunday. Reluctantly, Yuuta accepts and goes. That day, Yuuta is welcomed by Miu, the second oldest girl, who waits no longer to invite Yuuta to come in.
Now, Yuuta starts feeling a little bit uneasy, since her sister and her husband are not at home. Miu tells him that they won’t be coming soon, and that they were told that their uncle would take care of them.
Then, Yuuta meets Hina, the youngest of the girls. She is three years old and refers to Yuuta as her Uncle, but her pronunciation isn’t close to the real word. Yuuta asks Hina to call him big brother or something like that; he doesn’t want to feel that old.
Finally, Yuuta tries to settle down and play with Hina. He goes to the bathroom just to find out that Sora, the eldest of the girls, is changing clothes. Both are shocked and stay put without a word, until Sora screams out loud because Yuuta sees her partially naked.
Yuuta Segawa is a college freshman just starting a new life in the School of Literature at Tama University. His parents passed away when he was young. As such, he was raised by his sister, Yuri.
