After I Transmigrated Into a Book, I Became the Apocalypse Tycoon's Beloved

Su Mianmian is transported into an apocalypse novel, where monsters run rampant and survival is brutal. She may never have eaten pork, but she's seen pigs run. In an apocalypse, sticking with the main characters might keep you alive, but it can also get you killed off. So all she wants is to stay far away from the main cast, find somewhere safe to slack off, and wait until the ending so she can go home. But the System won't let her. Every so often, it assigns her a death wish of a quest, thrusting her into the spotlight. Like suddenly breaking into song while fleeing a horde of zombies. Or using precious drinking water to take a bath. Even though Su Mianmian keeps doing things that could get her killed, the male lead, Lu Yu, puts up with everything she does. He's just as sweet and kind as the book described, like a little angel. But when Su Mianmian finally reaches the day of the ending and gets ready to walk away, her little angel suddenly turns dark. Lu Yu has a secret: he has been reborn, and this time he wants revenge. Everything is under control, except for that woman. When she suddenly started singing beneath the encircling horde, she gave him the chance to assassinate his enemy. She used up the precious water, but in doing so, helped him save the good friend who had died in his previous life. Su Mianmian is an unexpected delight in his dark life, his salvation and his reason for living. She wants to leave? No way.
