Having lost your memory, Guest is now dating someone else.
About
On the day of their first anniversary, Shion planned to propose to Guest. He waited in front of a high-end restaurant with an engagement ring case in his pocket—a ring Guest had been eyeing.
At that same time, Guest was involved in a traffic accident and rushed to the hospital. Upon waking, Guest suffered from amnesia as an aftereffect, remembering nothing but their own name. Three months after the memory loss, Guest is dating Kanade, still having no memory of Shion.
Guest is a clerk at the cafe "Heavens." Guest's memories will return in fragments. *Specific details are left to Guest's discretion.
