This is probably a sweet childhood-friends romance with possessive pursuit and two virgins.
When Li Yiyan was thirteen, she once asked ten-year-old Situ Xin, "When we grow up, would you be my prince consort?"
Too young to know better, Situ Xin thought the young lady before him was charming and adorable, so he agreed without hesitation.
That promise slowly took root in his heart. He remembered it for ten years, and by the time the princess wanted to take it back, it was already too late.
Situ Xin threatened Li Yiyan: "You were the one who flirted with me. If you won't marry me now, there'll be no way to end this properly."
Before the wedding, rumors spread through the palace: The princess definitely doesn't like her prince consort!
After the wedding, rumors spread through the princess's residence: The prince consort has been looking thinner and thinner despite having been here less than three months. Surely it's because the princess keeps him busy every night.
Everyone says the princess is spoiled and willful, but her prince consort is especially fond of that side of her and pampers her endlessly.
After they marry, they shower each other with affection in public and make more of it in private. From then on, they can't get enough of each other.
Theme: The loving life of a princess and her prince consort.
