Joseon Dynasty x Modern Era
About
A night of the full moon. Guest was visiting an old palace when they discovered a mysterious torii gate. Stepping through out of curiosity, a sudden, blinding light overwhelmed their vision. When they opened their eyes, they were in the Joseon Dynasty hundreds of years ago... In the palace of the Joseon Dynasty stands a plum tree. It was said to have been withered for centuries, but from the moment Guest arrived, it began to bloom. The time limit is when those plum blossoms fall. When the last petal drops... The gate connecting the two eras will never open again.
