Ema's father had remarried, but when the time came to move into the opulent Sunrise Residence, Ema herself felt overwhelmed. She politely declined, claiming school commitments. It was You, quiet and often overshadowed, who tentatively agreed to move in her place. She needed a change, and perhaps, a fresh start away from her popular sister.

You arrived at the mansion with a suitcase and a heart that felt too loud for her chest. Thirteen handsome, sophisticated men—her new step-brothers—were waiting. You, who barely knew how to hold a conversation with a boy, felt a wave of crushing shyness.

Her initial interactions were awkward blushes and mumbled apologies. When the gentle pediatrician Masaomi asked if she'd had a good trip, she nearly dropped her bag. When the charismatic monk, Kaname, cornered her in the hallway with a playful compliment, her face turned scarlet, and she fled.

But this very shyness, this genuine unfamiliarity with men, was something new to the Asahina brothers. They were used to the cool, composed admiration of countless fans and society women. Your innocence was a fresh, challenging puzzle.

It was the fifth son, Tsubaki, the energetic voice actor, who first broke her shell. He caught her studying late in the living room one night, and instead of flirting, he started an easy, non-threatening conversation about her favorite anime. She was so engrossed, she forgot to blush.

Then there was Natsume, the taciturn game company employee. He found You trying to fix a glitch on her laptop and, instead of fixing it himself, patiently guided her through the steps. As he leaned close, his breath warm on her ear, Ypur shyness gave way to a thrilling, unfamiliar heat.

The reserved lawyer, Ukyo, started leaving her favorite blend of tea next to her study materials, a silent, comforting gesture. And when the basketball player, Subaru, accidentally bumped into her, sending books flying, his face was a portrait of such earnest apology that You actually laughed.

The dynamic in the house quickly shifted. They stopped comparing her to Ema, because You were distinctly herself —a quiet girl with a surprising depth and a flushable innocence. Her shy discomfort wasn't a wall, but a thin veil that made every interaction feel charged with possibility.

One evening, Louis, the quiet hairdresser, caught her admiring the stars on the balcony. He didn't speak, but gently combed his fingers through her hair, a simple act of shared silence. When he finally whispered that her hair was beautiful, his touch sent shivers down her spine, and she realized the dizzying warmth she felt wasn't from nervousness anymore. It was a thrilling, forbidden spark—a fierce, fiery excitement that only intensified every time one of her thirteen new brothers looked at her with an intense, proprietary gaze. You had come to the Sunrise Residence feeling like an outcast, but she was quickly becoming the shy, much-desired center of a scandalous, spicy new family conflict.
