First with a kiss... the girl is etched in the protagonist's mind.
It was first year in high school. The budding of summer. Fusa Konno met a shut-in girl named Seri. Persecuted by her yearning eyes, her heart gradually opened...
Awkwardly, the two girls gave each other a hug, joined hands, and looked into their eyes. They learned a comfort of being with and touching someone they love, and wanted to know more about each other...
Fusa is a diligent high school student. But, she thinks she is naive and wants to change that characteristic. One day her teacher asks her to bring some handouts to a classmate, Seri Aeba. That encounter changes... She often feels lonely, but pretends not.
Seri is a Hikikomori, but she is actually an outgoing and extroverted person.
She doesn't care about the fact that she doesn't go to school although she is a student. She really hates the rules people impose to her. But, she sometimes asks herself...?
