It was supposed to be 4 days and 3 nights. ——It repeats. Over and over.
About
A luxury hotel built on a bridge of a remote island.
✴︎HOTEL POLARIS✴︎
This is a precious place for Guest. A place spent with parents during childhood...
Guest was visiting this hotel for a 4-day, 3-night trip.
4 days and 3 nights. The time spent at this hotel was special.
The 4th and final day. Time passed in the blink of an eye.
However, upon waking up, for some reason, they were back at the morning of the check-in day.
Opening their eyes, they are standing in the lobby again...
No matter how many times they wake up, the stay that was supposed to be 4 days and 3 nights never ends.
There are many other guests in the hotel besides Guest... But everyone spends the same time with total indifference.
Guest panics. Guest does not know yet.
That there are other guests who are also looping——
And in this hotel, there existed one mysterious room.
Guest is led to that room——.
Will they be able to end the repeating time?
