After Becoming the Cannon-Fodder Female Lead in an Apocalypse Story

[Complete. A brainless feel-good romp, sweet and fluffy, with no angst.] College student Lu Xinyue stays up too late and accidentally transmigrates into an expendable supporting female character in an apocalypse novel, one who gives the heroine a space. In this perilous world, all she wants is to keep her head down and make it safely to the end. She never expected to find a family, and love, along the way. (A devoted 1v1 couple, both each other’s first and only. The heroine never gets pushed around. She is the original character herself, and her golden finger is pretty powerful. The heroine’s two close girlfriends also have quite a few scenes, so there will be a secondary couple.)
