Seijo ga Kuru kara "Kimi o Aisuru koto wa Nai" to Iwareta node Okazari Ouhi ni Tesshiteitara, Seijo ga 5-sai datta node Zenryoku de Aishimasu!!

This light novel series, written by Miyano Miyako, originated as a web novel published on the Japanese platforms Shosetsuka ni Naro and Kakuyomu. It belongs to the popular 'reincarnation' and 'villainess-adjacent' subgenres of Japanese light novels, which typically feature protagonists navigating complex court politics after being sidelined or maligned. The narrative follows a woman who, upon being told by her husband that he cannot love her because a saint is arriving, chooses to live a quiet life as a decorative queen, only to discover that the saint is a child, leading to a shift in their relationship dynamics.

The physical light novel volumes are published under the PASH! Books imprint, which specializes in light novels that often lean into lighthearted romance and fantasy tropes. The series has been received as a comfortable entry within its genre, praised for its focus on the evolving domestic life of the protagonists rather than strictly adversarial conflict. Like many titles in the PASH! lineup, the series relies on detailed character-driven illustrations that define the visual aesthetic of the franchise, helping it resonate with readers looking for low-stakes, character-focused storytelling.
