Katarina short-circuits every isekai survival instinct by deciding doom flags are meant to be befriended, not avoided. She accumulates a rotating cast of people who want to marry her instead of kill her, and somehow that's the actual plot, not a side effect. The show knows its villain protagonist is supposed to fail spectacularly, so it turns her into someone too genuinely kind to trigger the apocalypse, and watches her accidentally win by accident every single time.

Katarina Claes, daughter of Duke Claes, takes a hard blow to the head and suddenly remembers her past life as a teenage girl in Japan. She realizes her current world matches Fortune Lover, an otome game she once played, and that she has been reborn as its villainess, the rival who torments the heroine. Every route in the game ends in exile or death for her character. Using what she knows of the story and her own wits, Katarina sets out to dodge each doom flag, beginning with ending her engagement to the prince. Based on a light novel, this reverse-harem romantic comedy blends fantasy and slice-of-life fun.
