Kao ni Denai Kashiwada-san to Kao ni Deru Oota-kun

Kao ni Denai Kashiwada-san to Kao ni Deru Oota-kun, written and illustrated by Azuma Fuyu, originated as a serial in the Japanese magazine Manga Time Jumbo before transitioning to online serialization. The series explores the dynamic between Kashiwada-san, whose stoic expression hides her true feelings, and Oota-kun, whose face transparently displays his emotions. It is a quintessential example of the 'poker-faced heroine' trope prevalent in modern romantic comedy manga.

The character designs were crafted to emphasize the visual contrast between the two leads, utilizing a clean, accessible aesthetic that highlights the comedic timing inherent in the misunderstandings between them. The series was well-received by readers for its lighthearted tone and consistent character growth, leading to the collection of its chapters into tankobon volumes that have become staples of the slice-of-life genre.
