Days That Pass By

Sugisaru Hi (過ぎ去る日)

After Hina's departure, Yōta attempts to move on with his life. While he is at school, Yōta encounters Hiroto, who claims to be a new transfer student. He then hangs out with Yōta and his friends. Several months later, however, a frustrated Hiroto calls out Yōta for not understanding why he befriended him. Just as he is about to leave, Yōta catches up with him after he realizes Hiroto was recreating the days he spent with Hina. Hiroto reveals that Hina is alive and he knows her location. 

That night, he takes Yōta to the Yamada Sanatorium where he gives him a false identity as a research assistant that is good for two weeks. Inside, Yōta meets Shiba, a visiting researcher, and she takes him to see Hina. There, Shiba reveals that cranial surgery was performed on Hina and she has an extreme fear of men. Seeing Hina's condition agitates Yōta.
