Plot.
Hotaka likes to see his crush Niki swim from the window of the manga club. That day, the coach of the swimming club tells him that he needs to at least swim once to qualify, unlike the previous year when he just took the theoretical test without actually performing anything physically. His coach, however, knows of his self-consciousness about the large scar on his chest due to a heart operation. He assures him that no one will be present to witness his swimming except himself. Misfortune befalls Hotaka when the coach commits a clumsy mistake by calling everyone at the time. While he trembles out of water, Niki offers her hand. In his self-consciousnesses and nervousness, he slaps her hand away multiple times. Hotaka blames his father for having a weak heart and apparently, they have cut off all ties with his father's family, after his demise. Niki seems to have suffered a similar fate when her father left them alone. She also learns of Hotaka's past when he nonchalantly wrote about it in an article in the manga club magazine thinking that no one would read it anyway, titled "How I lost my father twice". Niki relates to Hotaka's situation and they confess their love for each-other after overcoming many doubts about each other.
On their date in the summer festival, Niki asks about Hotaka's actual surname having changed it to his mother's after his father was gone. Hearing it, she runs away and calls her mother angrily, ordering her to pick her up. She then curses her mother with tears in her eyes. It turns out that she is the child conceived in Hotaka's father's second marriage, after he had left Hotaka's mother. The boy she curses everyday and deems the one who took away her father is none other than Hotaka. Following this revelation, she feels guilty of falling in love with her own step-brother and kissing him. As such, she cuts off all ties with him. When Hotaka approaches her, she gives him the cold shoulder and tells him never to touch her again.
Hotaka, in a state of confusion and sadness, goes to the house of his father in the hills, one of the keys to which was given by his paternal grandmother. When he reaches there, he finds Niki coming out of the door. She tells him everything: how he is her brother and asks him to leave the house to her as a compensation for stealing her father from her. He consents and leaves in agony.
Not a day after, the weather has suddenly turned bad with an impending typhoon. Hotaka, without any further delay and acting entirely on his resolve to save Niki, bikes to the house in the hill. She is there and relieved to see Hotaka. Her scooter has unable to cross the worsened road due to the rain. Hotaka offers his hand and she takes it. Together, they venture through the forest in the heavy rain until a gleam of light is seen, which he says is their father guiding them. They finally reach the safe zone.
In the relief camp, Hotaka's mother comes to visit them and she finally accepts Niki. Hotaka, witnessing the emotional scene, cries in joy. Hotaka starts believing in his father, that he gave up his life so that his son could save Niki.
After a few days, Hotaka and Niki have returned to their normal lives. Apparently, Hotaka and Niki had a dated for a short while and had an awkward breakup. At least that's what they decided to leave as the public story to prevent everyone's questioning and therefore keeping their actual relationship a secret. They still share a close relationship, although as brother and sister. This conclusion is brought about by the comparison between sunlight (Niki) and rain (Hotaka). Together, they are the well-spring of all life. However, between them, no flowers shall ever bloom. For them, all of eternity shall be evergreen. Hotaka and Niki vow to always be there for the other. They end their short adventure with a heart-wrenching conclusion, uttering to each-other: "To you, I give eternity".
During the course of their story, On-chan and Soga also managed to confess to each-other after a lot of struggle, given the state of affairs between Hotaka and Niki. They are going out in the final scene.
Reception.
On Anime News Network, Rebecca Silverman gave volume 1 an overall grade of B+, calling it "a nice introduction to a story that has more going on beneath the surface than it at first would appear."
