I was reborn as a princess in the world of an otome game, with memories of my past life.

Wait, what? I'm the heroine's love rival? No way! I have zero intention of falling in love with any of those losers, because I've set my eye on a support character–the Commander of the Royal Knights!

Except the heroine–after being reincarnated in this shitty game where the support characters are way better than the love interests–is threatening to destroy my own life with flags, and I'm determined to strike them down!

Who cares about being cute?! Rosemarie is a young girl who got reincarnated in the world of a dating sim. That game was famous for being a crappy game full of hopeless men! She has a bad feeling about it, but she has no time to waste getting upset about it! She's going to change the peculiar dateable character for the better and meet the man she really loves at all costs!
