Otonari-san wa Konyakusha (Kari) - 2-kagetsu Dake no Koibito ga Naze ka Watashi ni Amai

Otonari-san wa Konyakusha (Kari) - 2-kagetsu Dake no Koibito ga Naze ka Watashi ni Amai is a light novel series written by Matsuzaka Rio. Emerging within the competitive landscape of Japanese romantic light novels, this work centers on the premise of a temporary engagement—a popular trope in modern shojo and seinen romance literature designed to explore the tension and emotional growth between characters forced into intimate proximity. The series aims to bridge the gap between initial reluctance and genuine affection through the lens of a strictly defined, time-limited relationship.

The character dynamics and narrative tone reflect the current industry trend of focusing on low-stakes, character-driven domestic romance. Matsuzaka Rio utilizes a lighthearted approach to the ‘fiancé for now’ setup, emphasizing the contrast between the characters' public contract and their private interactions. As part of a genre that relies heavily on digital distribution and serialized web platforms before reaching print, the series has been received as a comfortable, dialogue-heavy entry that caters to readers seeking a mix of sweetness and incremental romantic development.
