Ever since Bai's birthday, the existence of [Gate] appeared, a place where one needs to try his best to escape from the door before he can wake up from the "dream".
There are two kinds of [doors]. One is the small door, which has no restrictions and can suddenly appear in Bai's world at any time.
The other is the [door] that opens on his birthday, a door that Bai can easily end as long as he goes in and becomes a guest.
But this time it was the twelfth [Gate] that Bai passed through, but he encountered something different from usual.
Intention: Spiral upward, continuous advancement, only then can it end
