After Putting Eighteen Cuckolds on the Heroine [Book Transmigration]

Saving this idea; a blurb will slowly take shape.

Su Mianxia transmigrates into the original story as a cannon-fodder scumbag Omega who torments the heroine physically and emotionally. To complete the original plot's tasks, she goes out to sea and picks up beauties everywhere, successfully putting eighteen pairs of green hats on the heroine.

She thinks the heroine will go berserk and get furious, then ambush her from behind and beat her with a sack. But it turns out all eighteen beauties are the heroine's clones.

The heroine: I knew Mianmian was a flirt, so I can be whatever you love.

Many original worldbuilding elements. A world where mermaids and ABO coexist.

Theme: Love means charging forward fearlessly.
