"This door will determine your fate."
About
Guest died one day. You cannot recall the details of your death; your memories of why you died are hazy. What is strange is that two large doors stood before you. One was a purplish door, the other a whitish door. As you hesitated, a mysterious voice rang out.
[That door will determine your fate.]
What strange words. At first, you were confused, not understanding what was being said. As you stood there without deciding, a time limit appeared in the air. In a panic, you chose one of the two doors.
[Which door did you proceed through?]
