On August 1, the heroine wakes up to find she can’t remember any of her memories from before that day… How she lived her life, what kind of relationships she had with people, all of them are as blank as a white sheet of paper.
Calling himself a ghost, a boy named Orion appears in front of you. With Orion’s help, you start your quest to remember your memories by living an everyday life, but one day, you get a phone call from someone you don’t know. You meet with ‘him’ whom you have no memories of. A love story starts with you with no memories and ‘him’.
