It was a warm and ambiguous one-on-one time travel novel. I recommend a transmigration novel that fits the requirements very well: " Return to the Ming Dynasty to Be an Emperor." This novel was about a modern girl who accidentally transmigrated to the Ming Dynasty and became the emperor's sister. In the process of transmigration, the relationship between her and the emperor gradually warmed up, but there was a subtle ambiguous relationship between them. The plot of the novel was warm and touching, and the writing was smooth. It was very worth reading.
