Babel Kyusaku(2020)

Babel Kyusaku is a Japanese series set in a mysterious five-story apartment building where aspiring screenwriter Kusaku Mitsuhiro takes on the role of manager. He soon discovers that Babel exists as a hidden world within the building—a place where abandoned dreams come true and reality bends to desire. The tenants are all people who surrendered their ambitions in the real world, now trapped in this false paradise. The catch is brutal: speak the word "Babel" aloud and you forfeit any chance of ever returning to reality. As Kusaku navigates the building's strange rules and its desperate inhabitants, he must decide whether to embrace this dream-made-manifest or fight to escape before it's too late.
