After Hina's departure, Youta attempts to move on with his life. While he is at school, Youta encounters Hiroto, who claims to be a new transfer student. He then hangs out with Youta and his friends. Several months later, however, a frustrated Hiroto calls out Youta for not understanding why he befriended him. Just as he is about to leave, Youta 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 Youta to the Yamada Sanatorium where he gives him a false identity as a research assistant that is good for two weeks. Inside, Youta 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 Youta. (Source: Wikipedia)
