Hibari ga Naitara Tsukamaete

Enomoto is now a college student, and he often recalls the time he spent with his childhood friend Shimura, who was always by his side until six years ago. A sudden transfer caused an abrupt separation, and Enomoto never found out where Shimura had gone, nor has he heard from him since. Their paths unexpectedly cross again when Shimura appears in Enomoto's college Philosophy class. While Enomoto is overjoyed by the reunion, Shimura seems to have mixed feelings about it.
