Forget Me Not Volume 5 (2016)

Serizawa is a man in his twenties who works at a divorce attorneys office. One day, while walking home from work, he is involved in an accident, and a woman carries him to an ambulance. Later, still groggy in the hospital, he receives a phone call from the woman who saved his life. She knows intimate details about him, but he cannot identify her. Serizawas gentle personality has attracted many girls since childhood, though he is far from perfect. Is the caller someone he loved and lost, or perhaps someone he wronged and never managed to make amends to?
