"If you never leave me, I will depend on you for life and death." This is a promise that is widely circulated on the Internet and is even a bit tacky. But it entangled two souls and three people's lives.
"I'm not a good person. Even to her, I finally broke my vow. After waiting for so many years, I can finally make up for this. I will never give up."
"What, he wants to kill me because of such an unknown oath. I'm just here to make money. If you think I have the heart of an adult, then he has lived for so many years in vain. After all, he has been around since the Republic of China."
True, neither he nor she had much to shine with. He covets her soul, and she wants to earn his money. There is no way to save these two people.
