I, Masako Sakai (an ordinary office-lady in her twenties), fell to my death from the stairs of a train station right after my boyfriend dumped me. But when I woke up, I was reborn as the villainess in an otome game called "Do-S Ouji Ranbu: Choose Me" in which all the male characters are sadistic boys...

I lived a modest life, unable to be my true self, and then to die so easily was just awful! In this life, I'm going to live the life I've always wanted! I'll do whatever I want before I die! The typical tsundere prince, the spoiled little devil of a prince, the muscular gorilla-type knight-commander, and the sharp-mouthed chamberlain... I'm going to make them all into my playthings!
