Kansai boy Kamishiro Yu transferred to Tokyo private Sakuraba High School due to family changes. His life was completely rewritten by a "Thursday cycle".
In the gold dust floating in the empty classroom, he met Hoshino Shio, who always carried a sketchbook - that mysterious girl who could turn back time with a gear brooch in the equipment room at dusk, and crack the Morse code with lemon candies under an umbrella in the rainy season.
Every Thursday at 3:03 pm, there is always a glimmer of fantasy seeping into the daily folds of the campus:
The borrowing records from 1999 among the old books in the library, the quantum entangled body temperature in the mercury column in the health room, the space-time wormhole connecting twenty years behind the convenience store freezer...
When the young Takoyaki promise hit the truth about the rust of the gear device, Kamishiro Yu gradually discovered that behind the lonely figure of Hoshino Shio, there was an unsolved mystery that spanned two generations:
Why do the cherry blossom specimens in her sketchbook always stay in the spring of 1999?
Is the looming scar under the collarbone related to the laboratory accident fifteen years ago?
And every time he tried to touch her fingertips, the second button of the uniform would always be hot, as if it sealed a promise about "forever"...
This is a time and space adventure fueled by heartbeats,
It is a cosmic love letter written by a boy and a girl on the Sakura Front.
When Thursday's cash register is fixed in eternal coordinates,
Their story will eventually become the subject of a surveillance camera at a convenience store in Tokyo.
A montage of youth that is soaked by the rain but never fades.
