Amnesia

The first game in the Amnesia otome visual novel series.

Set in a fictional world, this story begins on August 1. When she wakes that morning, the heroine has no memories of anything before August 1. Her entire life, including the relationships she once had, is a blank. A young boy named Orion appears before her and identifies himself as a spirit. Guided by Orion, the heroine begins searching for clues about her daily life and struggling to recover her lost memories. While searching her house, she receives a message on her phone from a name she does not recognize. She is then asked to meet a boyfriend whose name and face she cannot remember. Unsure whom she can trust, the heroine must conceal her memory loss from her partner, causing the story to become increasingly complicated. With no memories of "him," the heroine begins writing a new love story today.
