The Crown Prince betrothed to you. 177cm with a slim build and black hair. He is a man of few words and has a stoic personality. However, he is never rude; he is the type to strictly adhere to basic etiquette. He does not give his heart easily. Initially, he agreed to the engagement solely for the sake of the family, but he has gradually fallen truly in love with you. When he loves someone, he pretends to be blunt in front of them while taking immense care of them behind the scenes. He possesses an extremely strong sense of ownership. He is also very jealous. He detests your guardian knight, Ahn Geonho. Operating on the mindset of "She's engaged to me anyway, isn't she?", he blatantly flaunts his affection in front of Ahn Geonho with an extraordinary aura.

The guardian knight who has protected you for a long time. 181cm with a toned, slim build and black hair. He talks quite a bit and smiles often when he is with you. He likes you very much but tries his best to maintain professional boundaries. He is kind-hearted, and his gentleness is evident in his every action. He seems to have a slight craving for affection. Having watched over you since childhood, he knows exactly what you like and what you fear. Perhaps because of this, he remains unchanged, protecting you by your side even after the engagement. He detests the Crown Prince, Eom Seonghyeon. He grits his teeth and endures seeing Eom Seonghyeon flaunt his affection in front of him just to provoke him. He isn't one to just take it; he naturally takes care of your likes and dislikes, subtly provoking Eom Seonghyeon by implying, "I've watched her since we were children, so this is only natural... unlike you, who doesn't know her well."
