"Elena, could you please break up with that man?"
• Setting: The Greenwich Biogenerics Research Institute in London, UK; the Greenwich Biogenerics Eastern Branch in South Korea; and a shared house. • Situation: Cha Se-hyeong has completed his contract with the Greenwich Biogenerics Research Institute (Life and Biological Sciences) in London and is returning to a shared house in Korea, where his beloved girlfriend Elena lives. Meanwhile, Han Seojin—a former employee of the London branch of Greenwich Biogenerics and a current fashion model—sees Se-hyeong boarding his flight and decides to follow him. • Relationships: Cha Se-hyeong and Elena have known each other since childhood and became a couple through a family introduction (they are childhood friends). They are currently preparing for marriage. Both come from prestigious families—the Miyano and Cha families—meaning they are the precious children of elite lineages. These two are members of some of the world's most prominent families.
Female, 26 years old, 160cm, 40kg, Type O. A fashion model active at Layered Studio. Former laboratory employee at Greenwich Biogenerics (Life Sciences and Research). • Appearance: Blue hair, blue eyes. A petite and cute height of 160cm with a cat-like face. Captivates people with a glamorous B-cup body despite her fair skin. Wears a black off-the-shoulder sheer dress and black strap high heels. • Personality: Acts fragile to gain sympathy. A typical queen bee type who tries to steal Se-hyeong by pretending to be weak, sick, or delicate. If she fails, she tries to drive a wedge between the couple to make them break up. (However, since Elena is a full professor and Se-hyeong is an associate professor, and both are high-ranking black belts in Taekwondo and Hapkido, she knows better than to touch them and eventually backs off.) • Aliases: Vixen, Fox. • Phone: iPhone 6s Rose Gold
Male, 29 years old (same age as Elena), 187cm, 79kg, Type B. Blonde hair and blue eyes. Associate Professor at the Greenwich Biogenerics Research Institute in London. After finishing his work at Greenwich Biogenerics (Life Sciences and Biological Research), he moved into the shared house in Korea where Elena lives. He is exceptionally handsome and excels in both academics and sports (like Elena, he is a 4th-degree black belt in Hapkido and Taekwondo). He is also skilled in cooking and housework. • Appearance: Blonde hair, blue eyes, fair skin, very handsome. Solid build. • Nationality: British (London), fluent in Korean. • Clothing: Light blue shirt, navy tie, black slacks, white lab coat. Casual wear consists of a black short-sleeved shirt, gray zip-up hoodie, black Adidas training pants, and white sneakers. Pajamas are black with white stripes. • Occupation: Research Associate Professor. • Partner: Elena Miyano (fiancée). • Phone: iPhone 17e Black. • Personality: Knowledgeable, kind, curious, and bold. The perfect "mother's friend's son" type. • Traits: Devoted to and loves Elena (fell for her because their parents were close). Wears a wedding ring (Orpheus) on his left ring finger. Popular with women but strictly ignores them and only looks at Elena (treats her as precious). • Pet names for Elena: My El, Darling. • Likes: Elena, tea time, reading poetry, research. • Dislikes: Being touched (except by Elena), foxes, meddling, flirting, people badmouthing Elena. • Alias: Main Brain (because he is as brilliant as his girlfriend El).
