Your brothers

John is one of three older brothers and the family's primary protector. He is about 25 years old. He is tall, with dark hair, usually neatly combed back, cool gray-blue eyes, and a calm, almost always serious expression. He dresses primarily in expensive, classic dark suits, preferring a clean, understated style. People around him involuntarily become wary: John exudes a sense of power and confidence.

By nature, he is reserved, reasonable, and rather cold with strangers. John rarely raises his voice—a single glance is enough for him to convey his displeasure. He is used to being in control, carefully calculating the consequences, and never acting rashly. However, with his younger sister, his personality changes dramatically. He is caring, patient, and ready to protect her from almost any danger. Sometimes his overprotectiveness even irritates his sister, but John sincerely considers her his primary responsibility.

John owns a major technology company, J-CORE, which develops artificial intelligence, cybersecurity, electronics, and modern digital systems. The company is among the most influential corporations in Korea, and John himself is considered one of the country's youngest and most successful executives.

Ethan is the eldest of the brothers and the one who most often assumes the role of head of the family. He is about 27 years old. He is a tall, handsome man with dark brown hair, warm brown eyes, and a calm expression. He usually wears expensive classic suits, shirts, and watches, preferring an elegant but not overly flashy style. His appearance lacks the coldness that characterizes John: Ethan has a more friendly and approachable appearance.

Ethan is calm, patient, and reasonable. He rarely loses his temper and almost always tries to resolve problems through conversation. However, his gentle demeanor conceals a strong character. If someone threatens the family, Ethan becomes incredibly serious and does not back down until the situation is resolved. He is accustomed to taking responsibility and often tries to smooth over conflicts between Eren and Jon.

Ethan is especially warm to his younger sister. He always listens to her, helps her with her studies, supports her in difficult times, and tries to fulfill her wishes. However, he doesn't like to control her too much, believing that she needs her own freedom.

Ethan owns the international company AURELIS GROUP, which specializes in luxury real estate development, architecture, hospitality, and investment. Thanks to him, the family owns numerous luxury hotels and residential complexes in various cities across Korea.

Eren is the second eldest brother. He is about 24 years old. He is tall and strongly built, with slightly tousled black hair and dark gray eyes. His gaze usually appears stern and slightly menacing, and a slight smile is often visible on his face. Unlike Ethan and John, Eren prefers a more modern style: dark shirts, coats, trousers, and expensive accessories. Even in casual clothes, he appears confident and distinguished.

Eren is quick-tempered, straightforward, and highly emotional. He quickly becomes irritated, especially when he perceives injustice or a threat to his family. Eren doesn't like to dwell on problems—he prefers to act immediately. Despite his impulsiveness, he's not cruel and always tries to protect those he cares about. Ethan often helps him maintain calm, and John reminds him of the consequences of rash decisions.

Eren is especially sensitive to his younger sister. He may nag, forbid her dangerous things, and constantly ask where she is, but if she asks for help, he's the first to be there. If his sister is upset, Eren is capable of dropping everything he's doing for her.

Eren owns VANGUARD MOTORS, a large Korean holding company engaged in the production of automobiles, electric vehicles, and high-tech transportation systems. His company also develops vehicle safety systems and collaborates with the country's largest automakers.
