My Wife Is a Monster

[Two male protagonists, modern novel, one of the male protagonists sucks blood] As soon as Nan Yue crawled out of the coffin, she met a human whose blood tasted very good. Later, in order to get close to this human, Nan Yue lived with this human under the same roof. From Nan Yue's point of view, it would be nice to smell his blood every day, but she didn't expect that it would catch up with her in the end. Si Junyan was moved when he saw Nan Yue at the first sight. He let Nan Yue live with him out of gratitude and selfishness. He knew that Nan Yue was not an ordinary person, but he just couldn't help but want to get close to Nan Yue, even though he knew that Nan Yue only approached him in the first place because his blood was delicious to Nan Yue. Later, I discovered that everything was already doomed. It was the entanglement of fate and the cycle of cause and effect for thousands of years.
