Has the Prince Pledged Himself to Me Today?

The human-dragon hybrid female protagonist x the mortal male protagonist, warm and doting Chu Yunjing, the crown prince of the Chu Kingdom, met a strange girl one day. This girl was pretty good at everything, but she always said strange things. I don't know if I have read too many stories, but I always say that I have to pledge myself to save my life. Hmm... I want him to commit himself... A certain prince fell into deep thought when he looked at the little girl who was not even taller than his chest... It was impossible to give her body to someone, and he didn't like the little girl. Until one day, the little girl finally removed her horns and raised her head. Her first reaction was to reveal her true form and yell fiercely at someone: Ouch! A certain prince: Pfft... Qingruo flipped the table in anger, I am a fierce dragon, very fierce! Be afraid of me and cry! His Majesty the Crown Prince touched the other person's head skillfully, coaxing the person to change back and fell into deep thought again, as if it was not impossible to promise him with his body...
