One day a puppy comes to the house of Akari, who has just turned twelve, and was trying hard to act strong after her mother suddenly fell ill. She immediately falls in love with the puppy and names it "Socks" after the paws which looked like they had white socks on. Akari was together with Socks day and night. However, as Akari grows up, her feelings and interest moves away from Socks. Year by year, their distance grows, which also leads to her physical distance as she moves to a far off city, and must leave Socks behind to a childhood friend.

When middle-aged salary man Tsubakiyama suddenly dies, he leaves his family high and dry. But suddenly he's given another chance: a few days in which to return to Earth and straighten things out. The thing is, he's come back in the form of a strikingly beautiful young woman.
Working long hours in the emergency room, nurse Kana Aoshima befriends musician and frequent hospital patient Shogo Amami. Shogo's therapy visits for his muteness and blindness happen to frequently coincide with Kana's shift, which enables the nurse to get to know the handsome artist well enough to start falling in love with him. Fate intercedes, however, when Shogo is killed after being hit by a car - a development that utterly crushes Kana's will to live. Shogo's spirit is transported to heaven, where it is given the chance to return to Earth to assist Kana through her grieving and to renew her sense of faith in the world - with the only caveat being he cannot reveal his identity to Kana.
