Who Knows? I Just Want to Repay My Kindness but I Am Being Pestered to Become a Princess.

She is Shangguan Changle, a gold medal guard of the "Night Owl", an intelligence organization of the Great Zhou Dynasty. She has outstanding martial arts skills and a ruthless face. Three years ago, in order to repay the life-saving grace of a mysterious young master, she was willing to remain anonymous, sneak into the heavily guarded Prince Su's Mansion, and become an inconspicuous maid next to Prince Su, Jun Mo Yu. She had a good plan: protect him for three years, repay her kindness, then fly away and regain her freedom. He is Jun Moyu, the reigning King Su, who is regarded by outsiders as a frail, sickly and idle prince who has nothing to do with the world. No one knows his secret methods and monstrous ambitions. Over the past three years, he watched with great interest as the little maid next to him "clumsily" shielded him from open and hidden attacks, gradually seeing through the alienation and hidden skill beneath her calm appearance. At the end of the three-year period, Shangguan Changle left a letter of resignation and prepared to retire. But he didn't expect to be "invited" back to the palace by Jun Moyu that night. The usually "sick" prince trapped her in a corner, stripped off all disguises, and his eyes were hot and dangerous: "Chang Le, you stole my most important thing and you just want to leave like this?" Shangguan Changle (confused): "??? When did I steal something?" Jun Moyu (chuckles): "You have stolen my heart. Since you want to repay your kindness, how about... Pledge yourself to stay with me for the rest of your life?" From then on, Shangguan Changle found that he had repaid his kindness and became a princess, and the road to freedom seemed to be getting farther and farther. But Prince Su, who was cold and dignified in front of outsiders, turned into a clingy spirit in private, pestering her every day and asking: "Changle, do you like me a little more today?"
