She has traveled through time, but this girl can't remember anything, her name, family, or age (well, you can see for yourself). . . The point is: she doesn't remember anything! It doesn't matter, it doesn't matter, she knows a place where the treasure is hidden, but she can't tell anyone or touch it - it's so depressing! The girl's time travel, the girl's love, the girl who laughs with tears, the girl who makes people feel heartbroken!
