Just outside the back door of the house, in the outdoors、Suddenly

Just outside the back door of the house, in the outdoors、Suddenly, an unfamiliar staircase appears。even though they shouldn't be there normally、but old wooden and stone stairs shrouded in mist...。 apparently sweet music and scents drift up the stairs。but、you should never go up。Because they say it leads to another world or dimension.。once you climb、there's a possibility you'll never return to the original world。even if you count the steps、the story is that they change every time。
