A struggling concept café forbids sexual behavior yet pits pairs of attendants against one another to win the big spender who determines its survival. Manager Mio Ichijo is serious and trusted, believes careful service beats aggressive sales, and cannot hold alcohol; her results trail the college pair. Founding employee Kotone Toa understands every cast member but becomes a drunken kissing, groping, panty-removing menace. Too troublesome for promotion despite seniority, she remains an irresistible life of the party.
