Synopsis

Viscountess Brigid realizes she's been reincarnated into the world of a web novel after seeing her favorite idol in his childhood. Her ultimate idol, Nisha, grew up without knowing love and is destined to be killed by the protagonist as the villain. Determined to protect her idol's life, she tries to adopt him to shower him with all her love, but is told she cannot become an adoptive mother while unmarried. However, the ill-fated Marquis Diamid, rumored to never fall in love, proposes, "Why don't you enter into a fake marriage to become Nisha's adoptive parents?" She married without hesitation, but for some reason, her stepson became attached to her and her husband doted on her...!? A chaotic (tentative) family comedy in which she struggles using her otaku side and knowledge from her past life!
