In 1997, it was a hot summer. The streets of Nara are filled with the smell of lazy antiquity, time flows slowly, and the tremor from antiquity can be felt in the air. Like many teenage boys, the Aso twins, Gui and Junxiao, run through the winding lanes. At the next turn, fate changes in an instant. As if hidden in general, the elder brother Gui, who ran in front of him, disappeared out of thin air, which made the clock of Aso's family stop from then on. Five years later, the pain of the Aso family gradually healed. Jun (Fukuyong Yukuhei) is already in high school, and he likes each other with his childhood friend Xi (Bingzu Youxiang); his father Zhuo (Nagase Seihisa) specializes in his own career, while his mother Reiko (Naomi Kawase) is wholeheartedly waiting for the arrival of new life. One day, the police came to visit and brought a long-lost message of Gui.
