The Duke's Son Claims He Won't Love Me Yet Showers Me with Adoration

Elsa, sethe daughter of an impoverished noble family, receives a letter of marriage proposal from Julius, the eldest son of the ducal house of Royas. Though she is bewildered by the offer, she accepts for the sake of her family. However, after meeting the handsome Julius for the first time on their wedding day, he coldly declares to her, "I have absolutely no intention of ever loving you."

Even after hearing that her marriage is in name only, Elsa interacts cheerfully with Julius and the household staff, devoting herself to her vegetable patch and sewing. Julius, who has only known a cold home life, is baffled by her actions. One day, Julius's friend Rebeka invites Elsa to a tea party. There, she learns that Julius's birthday is near, and she starts to plan a surprise party.

After the official Sun Festival ceremony, Elsa heads out to join in the festivities at the invitation of her younger brother, Hannes. Julius is unaware of this, so when Serafina tells him that Elsa has headed into town with a man, he instinctively chases after her. Though he thought that theirs was marriage in name only, he realizes that at some point, he has begun to want to trust Elsa.

Elsa hosts a tea party where Serafina says, "Julius forgot this," and hands her one of the cufflinks she’d gifted him. Julius is happy to have it back, but uneasy about the fact that Elsa didn't seem concerned about it. As Julius considers the idea that Elsa doesn't see him as a romantic interest, she's visiting the castle, where Serafina's older brother Jarmo tosses some suggestive words her way.

Julius and Elsa visit a botanical garden. Julius considers himself adept with women, but for some reason, he struggles to find his footing with Elsa. Though their outing is filled with unfortunate events such as an encounter with Jarmo and getting rained on, Julius feels saved by Elsa's words: "I like listening to the sound of rain." But getting pelted by the rain leaves Julius with a high fever.

Julius is ordered to infiltrate a soirée hosted by Count Parnilla's family. He asks Elsa to accompany him as his wife. Elsa is nervous about attending her first soirée, but with Rebeka and Hannes's help, she fulfills her role as the wife of a ducal house. Then a very drunk man approaches her, seemingly targeting her the moment she's alone. The truth is that all it's part of Jarmo's scheme.

By chance, Julius learns about Elsa' birthday. He says, "I hope you'll let me celebrate it for you," and works desperately to clear his work so he can take Elsa to the opera. The splendid production and Julius's kindness combine to make Elsa's day a very special one. On a different day, while in town, Elsa comes across a rundown church with a children's home that is struggling to make ends meet.

Elsa has begun teaching at the children's home, but she hasn't been able to tell Julius because he's been busy. Julius manages to finish work early, and when he learns that Elsa is in town, he goes out looking for her, but what he finds is Jarmo chatting happily with Elsa. It is a mere chance meeting between the two, but when Julius sees them, he misunderstands the nature of their relationship.
