Ep. 13: And Then Start Running
In overthinking through flashbacks of high school, Kakeru remembers the isolation of being the high school coach's favorite. Pushed to his limit, Kakeru grabs ahold of Sakaki, but his friends come between them before anything can happen. Later they begin their grueling practice, but Kakeru can't stop recalling heavy memories from his high school days: a cruel past that pushed a group of elite runners to their breaking point. Recalling how he chose his own destruction, Kakeru agonizes over his past. That night, the sky is full of stars. Haiji appears next to Kakeru as he's hanging around by himself. Kakeru explains the backstory behind Sakaki's grudge towards him. Kakeru is finally encouraged to open up to his teammates, which strengthens their friendship even further. (Source: Wikipedia)
