The old apartment and the walls with poor soundproof make Satoshi Okada and Qixu (Kumiko Aso) inevitably share each other's voices. The coughing of seven threads, the beep of the humidifier, the intonation of French, the sound of wind bells going in and out, the sound of making coffee intelligently and the metal sound of keys touching while walking. The two, who are neighbors but have never met, share each other's lives because of these voices, and are comforted and cured when they are lonely and sad. While working in a flower shop, Qixu, a flower designer, was preparing to study in France, during which he was confessed by a convenience store staff, only to find that it was only a lie. The photographer's Cong is famous for shooting photo albums by popular star Shen Wu (Hiroshi Ikeuchi), but his heart is eager to take landscape photos. But Shen Wu accidentally disappeared and stranded the cunning Canadian landscape as planned. The injured two men decided to change and go abroad respectively. The two who have passed by each other countless times have not seen each other. At this time, the phone call from the hometown reunion seems to be connecting the two people.
