Was there a modern novel where the male protagonist was a plant, and the plot seemed to be about being with the female protagonist, exchanging his lifespan for it?

According to the novel, the male protagonist was a plant. It seemed that he had used his lifespan to quickly transform into a human form in order to be with the female protagonist. They could turn into all kinds of things. If the female protagonist didn't agree to their final confession, they wanted to kill the female protagonist and make her a specimen? In the end, the female protagonist agreed, and the male protagonist accidentally cut off a piece of her hair. In the middle, he gave the nectar to the female protagonist and lied to her that it was ordinary honey. In fact, it was the male protagonist's saliva because the male protagonist was a plant. Also, the male protagonist would turn into a ball at night and wrap the female protagonist inside before turning into a human in the morning. It seemed that the female protagonist did not know that the male protagonist was not human at the end. The male lead was a loyal dog in the early stages, but he turned dark in the later stages.
