Her husband is a severe mama's boy and has already lost interest in his wife, Koharu. Perhaps due to the stress, Koharu falls ill and collapses in the middle of a shopping trip. When she wakes up, she finds herself in an unfamiliar room. A kind man who happens to be passing by helps her and even nurses her back to health. Touched and attracted by the man's kindness, Koharu begins to visit him frequently from that day on.
