I'm a Banished Villainess, but I'm Accompanied by a Fluffy Creature. My Peaceful Life Starts

'''I'm a Banished Villainess, but I'm Accompanied by a Fluffy Creature. My Peaceful Life Starts''' is a reincarnation isekai.

Irene Oakwood is expelled from school, for supposedly being a troublemaker; though this actually due to Liliana, the heroine of Peach Wonderland, an otome video. Turns out Liliana is not the pure and kind girl from the game, but instead your typical high school snob who blames others for anything they do wrong. However, Irene breaks down in tears of utter joy at the news and happily leaves the school.

Irene is the reincarnation of a Japanese woman named Airi, who died due to her coworker harassing her at an escalator, while she was attempting to give her crush sweets; making her fall to her death down below. She attempted to stop the events of Peach Wonderland from happening and ruining her life, but as if the will of god, it was all in vain.

Unknown to Irene, she is the love interest of a foreign prince, Kago; he suffers lycanthropy that makes him turn into a wolf when it rains. They a year before Irene went to the school, where Irene gave what she thought was a stray puppy some cake; her kindness and cuteness made Kago fall in love with her ever since.

Trivia

 * The otome game is over at the start of the story, with Irene pitying the capture targets for not noticing Liliana's fake personality.
 * Liliana constantly harassed Irene in petty ways for no real reason.
 * True to the trope, the reason said villainess gets expelled and banished is due to several petty harassment. All of which in the 21st century would be OVERKILL.
