Have you recommended an ancient romance novel where the male lead feeds the female lead blood?

This novel was written a long time ago. I forgot the process. In the end, the male protagonist probably knew that the female protagonist was different from others. He loved her very much, so in order to detoxify her, he kept giving her and his blood without telling the female protagonist. It was not until the male protagonist died that the female protagonist realized why her lips had color. Just when the man was about to die, the female protagonist fed her blood to the male protagonist. In the end, the male protagonist lived, but there were bugs in his body. In order to eliminate the bugs, he had to drink aphrodisiac. That was probably what he meant. He had been searching for a long time, and he would be rewarded handsomely if he answered correctly. Thank you!
Note that the ending is that the male protagonist eats the male bug to detoxify the poison. After detoxifying the poison, he eats the female bug to kill the bug. The aphrodisiac is to make the two bugs mate. At the beginning of the book, the female protagonist was cold and did not understand love. It might have been even earlier than 2000.
