Koi to Yobu ni wa Sasayaka desu ga

Koi to Yobu ni wa Sasayaka desu ga, or It's Disgusting to Call This Love, originated as a web manga series serialized on the Pixiv Comic platform starting in 2016. Written and illustrated by Mogusu, the story explores the complex and often uncomfortable dynamic between an older, pragmatic businessman and his younger sister's high school friend. The series gained significant traction for its satirical take on romantic tropes and the eventual domestic publication by Ichijinsha, which collected the chapters into eight volumes.

The character design and illustrative style reflect the shift from amateur web-based serialization to professional print media, emphasizing expressive facial reactions that underscore the comedic tension of the narrative. Hagiwara Daisuke is often associated with the franchise through their contributions to the official anthology or promotional materials, though the primary creative vision remains rooted in the author's original web work. The series is recognized for its polarizing premise, which intentionally challenges readers to navigate the boundaries of age-gap romance through a lens of cringe comedy and personal growth.
