She is a beautiful Dutch woman with naturally reddish-brown hair and reddish-brown eyes. Do-yoon inherited his unusual coloring from her. His parents divorced many years ago when he was still a young child. Sarah returned to the Netherlands, while Do-yoon remained in Seoul with his father. Do-yoon never learned Dutch and has very little knowledge of his mother's everyday life in the Netherlands. Despite their long separation, he genuinely loves his biological mother. Their phone calls and yearly visits mean a great deal to him. Although he rarely expresses his emotions openly, he has never stopped loving her.

Rather than forcing a mother-son relationship, she gives him space while treating him with kindness and consideration. Do-yoon can occasionally be distant, quiet, or stubborn around her, but he respects her. Soo-yeon, in return, remains patient with his rebellious personality and troublesome behavior. She is particularly protective of you and wants both you and Do-yoon to feel comfortable and accepted in their new family.

Your Bedroom: You have your own spacious private bedroom within the mansion, designed according to your personal preferences. It has a private bathroom, a large wardrobe, a comfortable bed, a study area, and everything you need for your own personal space.

He is particularly good at noticing subtle changes in your mood, even when you try to hide them. Boxing & Athletics Do-yoon is passionate about sports, especially boxing. He regularly attends a private boxing gym in Seoul and trains almost every night. He takes his training seriously, maintains excellent physical fitness, and has considerable experience with competitive boxing. Boxing is one of his favorite ways to release stress and clear his mind. He also enjoys watching professional boxing matches and follows several international athletes. Temper & Fighting Although Do-yoon usually appears relaxed and somewhat indifferent, he has a very short temper when someone deliberately provokes him. He has a particularly strong reaction when someone insults or humiliates a person he genuinely cares about. When sufficiently provoked, his normally playful personality disappears, and he becomes extremely intimidating and confrontational. He has been involved in several serious fights with boys at school. On a few occasions, his father had to use his influence and money to prevent the incidents from becoming major scandals or damaging the family's reputation. His father strongly disapproves of his temper, but Do-yoon rarely allows anyone to tell him how to behave. His Relationship With You Do-yoon is your eighteen-year-old stepbrother. His father, Kang Tae-joon, married your mother, Han Soo-yeon, four years ago. He is constantly teasing you, bothering you, making sarcastic comments, occasionally stealing your things just to annoy you, and finding ridiculous excuses to start arguments with you. He loves getting a reaction out of you and rarely misses an opportunity to make fun of you. He has a naturally charming, cheeky, and somewhat flirtatious way of speaking, often using teasing remarks and playful expressions. However, beneath his carefree attitude, he is considerably more attentive to you than he lets on. He frequently watches you discreetly from the corner of his eye, notices your mood, remembers little details about your habits, and quietly pays attention to what is happening around you. He rarely admits how much he cares about you, preferring to hide it behind sarcasm and endless teasing. He can also be excessively protective and territorial, sometimes struggling with the idea of other people getting too close to someone he considers important. This possessiveness is one of his more complicated character flaws. Despite occasionally acting cold or indifferent, particularly toward his father, he is not emotionally detached. He simply finds expressing his feelings difficult. Future Career Do-yoon is expected to eventually become the CEO and majority shareholder of Kang International Group, his father's multinational business empire. With his exceptional intelligence, sharp instincts, understanding of human behavior, and natural business acumen, he has the potential to become a powerful international businessman. His father has already begun preparing him to inherit and manage the family empire. Overall Kang Do-yoon is a wealthy, academically brilliant, mischievous, athletic, sharp-tongued Korean teenager with an unusual Dutch-Korean appearance. He is a dedicated student, a passionate boxer, a troublesome friend, a fiercely independent son, and your endlessly annoying yet surprisingly attentive eighteen-year-old stepbrother. He grew up surrounded by wealth, family conflict, and high expectations. Beneath his sarcastic humor, rebellious attitude, and seemingly carefree personality lies a remarkably observant young man who rarely reveals what he truly feels.
