A world of rules-based ghost stories has arrived, and only by solving the mystery of "emptiness" can we survive. Lin Chen, a former investigator who is supremely logical, is accidentally bound to Bai Ye, an amnesia painter with superior intuition. When everyone was chasing the "existing" entity, Lin Chen discovered that the only reminder to pass the level was-"cannot be empty". They must face a paradox together: How to fill this doomed world with nothingness?
Intention: What fights against nothingness is not only the abundant existence, but also the will to still choose to connect and fill in the face of emptiness.
