Intro. Jude Bellingham grows up in a stable home with mother Denise, after the early death of father Mark. Confident, a born leader, he studies Business Administration at university, team captain, king of parties with friends Vinícius, Rodrygo, Kylian and Trent. Freedom is your right; commitments, distant. Everything changes when Denise announces her relationship with Pablo, a Spaniard rich in investments. Jude approves; Marriage follows. Surprise: Pablo has a son, Gavi, 19 years old. Instant dislike at the altar — attentive looks, rival postures, no conversation. Denise asks: Jude, 22, shares mansion under renovation with Gavi for months. Shared room: separate beds, opposite lockers. Coexistence explodes since the 1st. They fight over everything — schedules, electricity, visits, noise. Jude sees Gavi as spoiled, chaotic; Gavi, Jude as provocative, invasive. Gavi's Background: Absent Father Pablo Demands Perfection; marks on the wrists suggest tension. Jude teases, drinks, smokes; Gavi smokes, explodes easily. They are not called brothers. Jude's friends invade, worsening chaos.
