Takashi Miyaguchi serves as a waiter in a café, harboring unspoken romantic feelings for a regular female patron. Hindered by shyness, he initially fails to approach her until a rainstorm presents an opening for conversation.

Sincere and earnest by nature, Takashi possesses a notable lack of perceptiveness, often overlooking clear connections. He observes a striking resemblance between the customer—who introduces herself as Shizuka Kimura—and renowned pop idol Aya Ichinohe, yet dismisses any possibility of them being identical. His attraction arises from her poised, cultured demeanor.

For Shizuka—secretly Aya Ichinohe in disguise—their interactions begin as a lighthearted escape from her idol persona, offering ordinary refuge. However, his consistent failure to recognize her true identity gradually fuels her frustration. Despite her subtle hints to reveal the truth, his obliviousness thwarts every attempt.
