Sharon, the protagonist, is engaged to Cyrus, the second prince, who is whispered to be "a man who can only keep women around compared to his elder brother." Although it is a political engagement, Sharon has loved and pledged loyalty to Cyrus since childhood, and has been racking her brains over how to deal with Cyrus's "womanizing behavior," or rather, his "testing behavior . " She spends her days reading books and worrying... One day, she comes up with a method : "Sharon, what are you imitating?" "Prince, I'll spoil you to the best of my ability from now on." "No, that's fine, but why am I tied down?!" It's by pouring love so strong that he can't escape...!? "Prince, good boy, good boy... let me make you feel good with my hands." "Come on, come on, let it out... There there... You've done well, you've managed to get so much out..." Sharon pampers the prince until he becomes a mess, and Cyrus begins to feel at ease with Sharon. Things are slowly moving in a good direction for the two, but the First Queen's plot threatens to break off their engagement. Will she enter into a fake marriage with the older prince and infiltrate the royal palace to save the prince's life, or will she join the prince in becoming a commoner, knowing the hardships it will entail, or...? "Let's commit suicide together, Sharon." "Rather than let you be taken by someone and used, I'll kill you and then die myself." ※※※This is a happy ending※※※
