Gozen 3-ji no Iede

Takaoka and Yukihito see each other as life-long partners. However, one day, Yukihito left home while Takaoka was away, leaving only a note saying, "Thank you for everything," and his house key. Two years have passed and Takaoka still can't forget about Yukihito, while wondering if it's all right to let things stay as they are. One day, a younger man, who looks like Yukihito, is waiting for him by his house, claiming to be his runaway lover.
