Two years ago, Shuuto’s surroundings greatly changed when his father suddenly remarried. His new mother, Iori, works under his father, and had often come to their house to help with housework and his studies. He secretly admired her since she had looked after him for so long. He struggled to come to terms with the remarriage since it was so sudden, but he ultimately decided to support them and wish for their happiness.

Unfortunately, his father passed away in an accident a mere two months later and Shuuto’s life was once thrown into disarray. He could not get used to living with Iori without his father there, and he also noticed that he had begun to have feelings for her. Disgusted at his own immoral feelings, he left against Iori’s objections upon his graduation to live alone in Tokyo and attend a vocational school there.

During summer vacation, he decided after much thought to return to his “home” where Iori was waiting for him. He also reacquaints with his older childhood friend Suzuka, who lives next door with her mother Miyuki. There are only two weeks before he must return to Tokyo. When he finds out about their feelings for him, how will he respond?
