Female-Oriented Multiverse: Starting by Stealing a Bride

After transmigrating, he becomes the Marquis of Zhenbei of Great Wei. Just when he thinks his hard times are finally over, the System awakens, and it turns out to be an utterly useless cannon-fodder System. After learning that this is a world aimed at female readers, he acts decisively and changes the plot, boldly becoming the groom.

Just when he thinks he can spend his days reclining in the lap of beauty and wielding power over the world, the System starts trying to fix its mistakes. Fake and real heiresses, a treasure-attracting golden toad, and many other heroines from various plots crash into his life, making it ever more eventful.

(This is a harem novel featuring a wide variety of heroines from short dramas.)
