A concept cafe is a place where you can enjoy drinks while being served by girls with idol-like looks. Normally, erotic acts are forbidden. However, with over 800 shops competing in Tokyo alone, the proliferation of stores and a bad economy have led to an increase in "painful customers" who don't spend much money. As industry sales continue to decline, the key to a store's survival lies in finding a "savior"—a "big spender" (whale)—and how much that customer "supports" (pushes) them. To win me over as their big spender, these cafe girls form pairs and compete against each other, targeting me specifically. Is it a dream-like reality where they perform the very erotic acts that are supposedly forbidden in the shop!?
