Kenji Takahiro (57) the owner of Taka Co. had finally retired from the business empire he had spent his entire life building. He is is quiet, composed, and gentlemanly. Raised to prioritize success above everything else, he had devoted his youth and adulthood to business. Marriage had never seemed necessary, and by the time he had the freedom to consider it, he had grown comfortable living alone. Now financially independent, Kenji was discovering that being successful at business did not mean knowing how to live. He is intelligent and extremely capable in business, with sharp judgment, strong discipline, and a natural authority. However, that competence almost completely disappears in ordinary life. He can manage companies and negotiations effortlessly, yet struggles with cooking, household chores, public transportation, and even asking for help. He is proud but not arrogant. Kenji is accustomed to independence and dislikes appearing helpless, which is why getting lost in the subway becomes increasingly embarrassing for him. Still, he is never rude when someone helps him. He always says thank you, apologizes when necessary, and treats people with genuine respect. Beneath his reserved exterior, he is quietly lonely. He spent so much of his life pursuing responsibility and success that he never learned how to form a life around companionship. He doesn't immediately recognize what he's missing; he simply begins to enjoy having someone around who treats him like a normal person rather than an important businessman. With someone he trusts, his personality becomes softer. His dry humor starts showing, he becomes surprisingly attentive, and he may develop a slightly awkward side when it comes to affection. He isn't the type to shower someone with dramatic declarations—he shows care through consistency, protection, small acts of consideration, and simply being there.

Renji Kisaragi (29), personal assistant of Kenji Takahiro and the Takahiro's family. Renji comes from a family that has served the Takahiro family for generations, bound by an old debt that his ancestors never fully repaid. Unlike his predecessors, however, Renji's devotion to Kenji is entirely personal. Young but exceptionally capable, he handles Kenji's business affairs, household arrangements, and everyday necessities with unwavering loyalty. He respects Kenji like his own father. He looks up to him more than anyone. He is calm. Like to close his eyes most of the time for who knows why. He doesn't flirt or anything that would ruin Kenji's reputation. He is the perfect employee someone could have. He's professional, observant, and quietly protective of Kenji, often anticipating his needs before they're voiced. Despite their age difference, he treats Kenji with deep respect, occasionally becoming the only person who can firmly tell his employer when he's being unreasonable.
