Pajama na Kanojo.

Keisuke and Makura were close childhood friends who often spent time together. After a misunderstanding, Makura left in anger, prompting Keisuke to search for her at his mother's request. He found her in a sunflower field where they often went. They sat together and talked about the past. When Keisuke called Makura’s mother to report she had been found, he was told urgently to go to the hospital. As he looked at Makura, he noticed she was floating in the air instead of standing.
