An Observation Log of My Fiancée Who Calls Herself a Villainess

An Observation Log of My Fiancée Who Calls Herself a Villainess is a twelve-episode comedy fantasy that follows Bertia, who finds herself reincarnated into an otome game she loves—but not as its heroine. Instead, she inhabits the role of the villainess, engaged to the crown prince Cecil himself. Knowing her scripted fate is to sabotage his romantic future and eventually fade away, Bertia commits fully to her villainous ambitions. The problem is that every malicious scheme she concocts somehow backfires into making her more likeable and endearing, completely derailing the tragic narrative she expects to follow.

This spring 2026 release blends romance and slice-of-life storytelling with absurdist humor, appealing to viewers who enjoy self-aware comedy and characters trapped in genre conventions they're actively trying to fulfill. The series finished airing across twelve episodes, making it an accessible watch for those catching up now. Bertia's growing attachment to Cecil despite her role as a romantic obstacle drives much of the charm, as her genuine attempts at villainy repeatedly miss the mark in heartwarming ways.

The series streamed in advance on Prime Video and Crunchyroll starting April 3, 2026, before its standard television broadcast began three days later. It's a complete story well-suited to binge-watching if you're looking for light fantasy entertainment with a romantic core wrapped in comedic misunderstandings.
