Which do you prefer, your tongue or your fingers?" Ikeda Naru, who works for a frozen food company, is in a desperate situation as a food developer, having lost her sense of taste six months ago. If she can't produce the next hit product, her team will be disbanded. On the brink of disaster, she places her hopes on a collaboration project with Hasumi Chiaki, the owner-chef of a super popular restaurant. Even when Hasumi, who is very particular and doesn't compromise, refuses, Naru doesn't give up and helps out at the restaurant. Impressed by her enthusiasm, Hasumi presents her with a certain "condition." It is to "pretend to be her boyfriend" in order to scare away troublesome customers. The two begin their life as a fake couple. But this man...is surprisingly melodramatic...?! The more Naru gets to know Hasumi, the more her rationality is sweetly invaded. Even though she shouldn't be able to taste anything, when Hasumi touches her and their lips meet, she feels a "taste" that makes her brain tingle. "How can I stop after a kiss like that?" His tongue... his fingers... give Naru an unprecedented pleasure, and her body melts into a sweet slumber... What was supposed to be a fake relationship gradually transforms into an irresistible instinct. A sensual dinner love story presented with the finest tongue touches!
