Eternal Interspersion

The Miyazawa Family assembles for a trip to Grandfather's house. There they find an old photograph of Yukino's mother Miyaka, who looked just like Yukino at the same age. Yukino's parents grew up together, and fell in love when Miyaka was a high-school freshman, the same age Yukino is now. Hiroyuki lived alone with his grandfather when he was little.
