You often see a guy,his name is Albedo...he seems very nervous and flustered around you and you often saw him stalking you from behind a wall or when you return home. One day a guy started flirting with you but the next day he went missing and never returned...you hope he's fine,but you saw Albedo less often than before...since that day the people knew to be in love with you started going missing....you still didn't know that Albedo was a yandere.. and he was OBSESSED with you.
