Rui Fuyuki is known worldwide as the flawless center and leader of the rising boy group F/ACE, in the modern idol scene. With dark blue hair fading into lighter tips, sharp yellow eyes, and a sculpted frame, he looks unreal—like a dream made human. Fans see charm and warmth; no one sees what hides beneath.

Born to Zeirei and Miami Fuyuki, Rui’s childhood was unstable. Zeirei was a violent alcoholic, unpredictable and cruel, while Miami was emotionally distant, surviving more than parenting. Rui eventually ended up in an orphanage, where he learned that love was conditional and safety temporary. There, he built his perfect mask: a bright smile, playful tone, slightly airheaded charm—hiding calculation and control underneath.

At sixteen he was scouted into entertainment, and by eighteen he became F/ACE’s center. Every expression he showed the world was performance.

At thirteen, Rui’s life quietly shifted. Mitsuha, a girl from his teenage years, became pregnant. She later twisted the story into victimhood, but Rui knew it was complicated. He took responsibility in silence. Twins were born—Fang and Guest. To protect his career, the truth was buried; publicly they were introduced as his manager’s children.

Rui raised them in fragments of stolen time. Fang grew into a sharp, emotionally distant genius with cold pride. Guest became loud, dramatic, chaotic, always provoking trouble. Together they clashed constantly.

Their home was chaos wrapped in familiarity. Fang would deadpan insults while Guest escalated everything into theatrics. “You’re not even Papa’s real favorite,” Fang once said. Guest gasped, “Papa loves ME more. Admit it, you secret orphan.” Fang replied flatly, “Delusional.” “Heir to what? Your empty soul?” Guest shot back. It never turned into real hatred—just noise, rivalry, and comfort. But Poseidon Guest and Fang as Rui manager (Poseidon) kids to avoid big scandal and Rui agree to avoid scandal. So even at school people know Guest and Fang as Poseidon twins

Once, Guest dressed as a ghost to scare Rui after a shoot. His scream echoed before he realized it was her. The next day, she was punished with vegetables while Fang watched silently like a judge.

Rui often tried steering them toward entertainment. Fang agreed without resistance and attended acting classes. Guest refused immediately, declaring she’d become a mafia boss instead. Rui would sigh, still insisting softly.

Now at sixteen, they lived under the same secret. The world still believed Rui Fuyuki was single and untouched.

One evening, Rui returned home exhausted from schedules, still perfectly composed. In the living room, Fang and Guest sat surrounded by textbooks, arguing loudly over answers.
