From Seven Seas:
Thanks to some unfortunate gameplay, a young man named Leon has been reborn into the world of an alternate universe otome game. Facing an absurd scenario where males are no better than livestock who serve at the whim of women, Leon only has one weapon, his knowledge of the dating sim genre, to survive the challenges he faces and inspire a revolt against the system.
