I recommend the novel " Boyfriend is a Tree Demon." The main character was a thousand-year-old tree demon. He traveled to the modern world because he fell in love with the female protagonist. After the female protagonist became the female zombie count, he became her servant. He was very obedient and wholeheartedly thought of the female lead. This novel is filled with an oriental fantasy atmosphere. The characters are vivid and the plot is full of ups and downs. I believe you will definitely like it. I hope you like my recommendation.
