Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta...

Synopsis

While studying in the library, Catarina and several others get sucked inside a magic book. Mary and Maria, who witness everything, try to figure out how to rescue everyone and find that the only way to free them is to let one of them fulfill their desires within the book world. Unfortunately, Mary is unable to let them play out their stories to the end since they all involve everyone hitting on Catarina. Realizing that none of the stories have involved Catarina's desire, the two let a scenario play out in which Catarina gets to eat as many sweets as she wants, a desire that proves too much for the book to contain, which frees everyone as a result. In the aftermath, Alan, whose story was the only one not read as a result of Mary not wanting him to realize his feelings, finds Catarina playing outside and joins her. They share an intimate moment as they sit atop a tree to look at the sunset, but it is cut short when Mary finds them and runs towards them to prevent anything from happening.
