"Girls dating each other? That's completely out of the question!" At least, that is the firm belief held by Marika Sakakibara, a highly popular high school girl who has never once questioned her stance on romance. However, her unwavering convictions are suddenly put to the test when her beautiful classmate, Aya Fuwa, approaches her with an astonishing and unprecedented proposition. Aya offers Marika a deal worth one million yen in total: ten thousand yen every single day for exactly one hundred days. Her goal is straightforward yet shocking—she intends to essentially buy Marika's time to prove, beyond any shadow of a doubt, that a romantic relationship between two girls is entirely possible. Caught completely off guard and utterly bewildered by the sheer audacity of the offer, Marika finds herself unable to simply walk away from the arrangement. From that fateful day forward, the boundaries of their ordinary student lives begin to blur. What starts as a bold financial wager quickly evolves into something far more intimate, marking the beginning of their secret after-school rendezvous. As the days steadily tick by, Marika must navigate this unexpected arrangement, discovering whether Aya's relentless determination can truly change her heart within the span of one hundred days.
