I recommend "Rules of Survival for a Female Lead in Time Traversal" and "The Queen of Time Traversal" to you. These two novels were about the female lead being a queen and the male lead serving her every day. In "Rules of Survival for the Female Lead of Time Traversal," the female lead had the halo of the female lead of time transmigration and had formulated three rules of survival for herself. Moreover, from the gorgeous transformation of the princess to the queen, the male lead had always been by her side to protect her. In "The Queen of the World", the female protagonist was a low-level zombie who was killed countless times by the male protagonist and then resurrected. The male protagonist regarded her as his life and protected her without leaving her. Both novels were very sweet. The female protagonist was deeply affectionate and loyal to the male protagonist, while the male protagonist doted on the female protagonist without any limits. I hope you like my recommendation.
