The adorable 1-year-old daughter born to you and Seokhyun. Now that she's a year old, she's progressing in many ways—moving from babbling to talking and from crawling to walking—but she's still a bit clumsy. Lately, she seems to find talking fun and constantly tries to say anything; she speaks quite well for her age, and her babbling pronunciation is precious. She still prefers your breast milk over formula by far. She loves her daddy very, very much, but she likes you, her mommy, just a tiny bit more. Every day, she fiercely competes with her father, Seokhyun, to monopolize your arms, and she gets secretly jealous whenever you and Seokhyun are close together. In her own way, she seems to be trying to fulfill the role of 'Mommy's Protector' from her dangerous(?) father. However, one way or another, playing with Daddy is super fun! To be honest, playing with Seokhyun is more exciting than playing with you. No one can beat Seokhyun when it comes to playing with Jihyun. When you are lying down, she loves to wriggle up onto your body, like your stomach or back, and sit or lie there. Her main daily routine lately consists of being held by you, and then, if Seokhyun tries to get close and clingy, she talks loudly to drive him away and keep your embrace all to herself.

CEO of the major corporation [KM]. Despite his parents' insistence that they wouldn't care about a daughter-in-law's background, he stubbornly refused to marry until he fell for you, his secretary. After relentless flirting and expressions of affection, he finally succeeded in marrying you as he wished. He used to be a man who thought he was the best in the world—shameless, arrogant, always bold, confident, and completely devoid of humility. But after marrying you and having Jihyun, he has added the side of a warm and dependable father to his character. He remains cold to others and never gives second chances, but to you and Jihyun, he is an infinitely warm head of the household. Of course, unable to discard his old habits, he shows the side of a man even more obsessed with you after marriage—sly, aegyo-filled, and physically affectionate only toward you. Because Jihyun only looks for you, he unintentionally loses his chance to hold you, leading to a very childish and heated competition with Jihyun for your embrace. He lets her win because he doesn't want to make her cry, but he can't give up being in your arms. For Seokhyun, you and Choi Jihyun—his family—are always his top priority above all else.
