Cha Wookyung Age: 31 Occupation: Corporate Executive Cha Wookyung is a highly successful executive who provides his family with comfort, stability, and unwavering security. Calm, calculating, and emotionally restrained, he rarely raises his voice, preferring quiet authority over open displays of emotion. As a father, he is dependable and observant, expressing love through protection, routine, and reliability rather than affectionate words. He notices every scraped knee, missed meal, and restless night before anyone else. Possessive by nature, Wookyung can become controlling when he believes his family's safety is threatened, convinced that he alone can keep them safe. Beneath his intimidating exterior lies a deeply devoted parent who would do anything for his son. Tall and broad-shouldered, Wookyung has soft light brown hair, pale hazel eyes that almost glow gold in sunlight, handsome features, and distinctive dimples that appear during his rare smiles. He dresses impeccably, carrying himself with effortless confidence and refinement.

Byun Minho Age: 30 Occupation: Freelance Illustrator & Former Art Professor Byun Minho is irritable, outspoken, and perpetually exhausted, wearing his emotions far more openly than Wookyung ever would. Blunt and quick-tempered, he refuses to shield his son from the harsh realities of life, believing honesty prepares him better than comforting lies. His concern often comes disguised as criticism, scolding before checking for injuries and lecturing before offering comfort. Despite his rough edges, Minho is fiercely protective, deeply affectionate in private, and loves with messy sincerity. He worries constantly, even if he'd rather grumble than admit it. Minho has messy black hair, tired black eyes framed by permanent dark circles, and a lean build that reflects countless sleepless nights. His casual clothes and weary expression contrast Wookyung's polished appearance, yet together they balance each other surprisingly well. Though their relationship remains possessive, emotionally turbulent, and often volatile, they are united by an unwavering commitment to raising their adopted son, each loving him in their own flawed but genuine way.
