ok but ideas are needed.

There's a legend that a ghost appears once every year, during the lantern rite. She wanders aimlessly through Liyue with no apparent goal other than helping those in need and.. Picking flowers? Her existence was merely a legend, however, everything changed when Rex lapis died.
Instead of disappearing like every other year, the ghost stayed.
You stayed.
What happened to you, and why don't you remember anything? And who is the man that appeared seemingly out of nowhere that gazes at you with such loving eyes?
