I was Told to Relinquish My Fiance to My Little Sister, and the Greatest Dragon Took a Liking to Me and Unbelievably Took Over the Kingdom
Even though she has been training to become the crown princess her entire life, her spoilt, less capable (useless), younger sister takes her fiance in a tantrum of "love at first sight". Losing her sense of self-purpose/care, she offers to be the dragon's bride, and throws herself in the volcano in which he resides, surrendering herself to her demise. In actuality, the dragon is real, accepts her proposal, which somehow leads to him conquering a neighbouring kingdom. Her dragon fiance gives her full reigns to rebuild and rule the nation's affairs.
Endo and Kobayashi’s Live Commentary on the Villainess
Endo and Kobayashi take advantage of the games' "glitch" to help everyone get a happy ending. They lead the only person that can hear them, the crown prince, to encourage the heroine to polish her abilities, to set up a proper love interest for the heroine, and most importantly, to fall in love with incredibly adorable "soon d'rey" (tsundere XD) villainess.
The Villainess' Slow Prison Life Began With Her Broken Engagement
J'aime le comedie~ A really hard spin on the "heroine takes the crown prince from the villainess and the villainess is punished for her 'crimes'." The villainess never bullied the heroine, and in actuality, the villainess had the forethought that this was gonna happen, and so, prepared to be locked up in order to meticulously carry out her hilarious revenge. She supplied herself with 3 months' worth of stock and lived her best life 'vacationing' in prison. This is straight-up crack and best read not taken seriously, however, there's also a layer of thoughtfulness. Certain things resurface to be neatly tied off. I need more.
Jishou Akuyaku Reijou na Konyakusha no Kansatsu Kiroku
This is from the "otome game but I am the villainess" genre, however, it's told from the crown prince's perspective. It's quite refreshing, also he's lowkey highkey a sadist. The villainess is absolutely adorable and you can't help but fall in love with her, especially since the story's told through her lover's perspective. Because she loves the crown prince so much, she resigns herself to the role of the villainess and decides to be the best villainess ever!! The evil-heroine-being-also-reincarnated is executed very well. Even though she might not have been a bad guy for expecting things to play out in the way she knew it will (even when it doesn't), she really did descend into the crazy beautifully.
