Naoto, a “corporate slave,” and Ren, a “host,” meet at 5:00 a.m., at a beef bowl restaurant in Shinjuku's Kabuki-Chō.

A corporate slave whose day is about to begin and a host whose day has finally come to an end.
This is a morning routine story that depicts the only 15 minutes in which these two people, who live on opposite sides of the clock, intersect!
