The Female Side Character Who Transmigrated into a Book Mistook the Male Lead

Gu Yuening transmigrates into a book, an old-school melodramatic angst novel, and becomes a cannon-fodder supporting female character who doesn't even have a name.

She chooses to face the challenge head-on, cling to the male lead, and make sure he follows the plot so she can keep herself alive.

But... why does the male lead have a twin brother?!
