## Description
Ryou’s imouto, who was much younger than him, was becoming more and more like a woman. Before he knew it, he became sexually attracted to her and one day while playing hide-and-seek, he was unable to hold back his urges and ejaculated on her as they were hiding together in the storage shed. He felt guilty about it afterwards and left the village to live alone in the city.

Several years later, he returned to his hometown after being asked by his parents to help with taking apart the storage shed where the act had been committed. In the middle of the field of early-blooming cosmos was his cute grown-up imouto Asaka. His love and desire for her, as well as his childhood friend Aki, which had stopped on that day began to move once more.

“Welcome back, onii-chan. I’ve always been waiting for you.”

Led by the sweet fragrance of the cosmos, it was the return of his past mistake…

### Kirino Aki (桐野 暁)
The protagonist's cousin and  cousin and childhood friend of  [url=https://vndb.org/c65826]Asaka[/url]. She's an energetic, outgoing, and cheerful girl. She affectionately calls the protagonist “big brother.”

She used to be tomboyish as a child, but has since grown into a cute young woman with a distinctly feminine physique. Being at that age where she's infatuated with romance, she's developed feelings for the protagonist, who she's always been close with.

She's extremely easily embarrassed; even the slightest teasing makes her ears and face turn bright red.

At school, she belongs to the track and field club, which has only two members—she being the sole athlete. Her specialty is sprinting. She even practices on her own at school during summer break, giving her a healthy tan.

She's a dependable person who often looks after the village children in place of the protagonist, who left their hometown. She has never left this village.

### Kusunoki Asaka (楠木 秋桜香)
The protagonist's younger sister, who will be entering a higher grade next year. She's quiet and shy around strangers. Since childhood, she's been completely devoted to her big brother, always trailing behind him, hiding in his shadow.

She shows the protagonist how adorably she's grown, but both her heart and body are still too immature to be called a “woman.” Having always relied entirely on the protagonist and having few friends, she's also a bit more emotionally immature compared to other girls her age.

She has waited endlessly for her brother, who vanished suddenly and inexplicably from her life. Her affection for him is blind; he has always been the most important person in the world to her.

She carries a stuffed cat toy given to her by her brother long ago, never letting it out of her sight. Its name is “Chocolat-nya.”

Her fee for giving her father a shoulder massage is 20 yen per session.
