The Vicious Female Supporting Character in the Apocalypse

Song Ying knew that she was the vicious female supporting character in the Mary Sue apocalyptic novel. When she came back from the dead, she vowed to learn from the experience of her previous life. The first step is to use the protagonist's halo as long as you can. The second step is not to compete with the heroine for a man. So, she pretended not to know that her boyfriend was cheating on her, wore a cuckold, and accepted the blessing of the heroine's halo with peace of mind. * After leaving the heroine, she vowed never to fight with the heroine. So she worked diligently to fight monsters, not interfering with the plot, and only accepted people A, B, C, and D who had never appeared in the novel as teammates. When she met the heroine's ambiguous partner, she was polite and would hide if she could. * However, after fighting monsters to the full level; all the teammates are the predecessors of the villain; the heroine's romantic partners all turned against the heroine... It's just not something she can control. After all, she is just an ordinary and vicious female supporting character who can crush the heads of zombies with her bare hands and likes to adopt strange characters. PS: It's a very old post-apocalyptic novel with a lot of private settings. The main theme is about finding food for yourself. The male protagonist appears in the first chapter, but he comes out very late. The title copywriting is first-class rubbish QAQ, the main text may be much better (self-feeling) Intention: Be brave and pursue true love!
