Summer Loop Syndrome

Sixteen-year-old high school sophomore Tetsuya Kobayashi planned to spend the last two weeks of summer vacation with four close friends at the quiet Sakuragaoka High School. However, he unexpectedly becomes trapped in a time loop repeating from August 15th to 28th. As the only one retaining memories across cycles, he must leverage his keen observational skills honed through Go practice to identify "anomalies" during each iteration and intervene in his friends' actions. If he fails to make any discoveries within three cycles, he will face the ultimate fate of being permanently lost within the distorted spacetime.
