Open Up, Sis-in-Law, It's Your Brother-in-Law

On her eighteenth birthday, Hestia received a dating sim.

The male lead had red hair and dark eyes, a bright, easy smile, and a sharp, spirited gaze. He was so handsome she could barely keep her legs together. Hestia fell for him at first sight, rubbing her hands together as she vowed to get the perfect Happy Ending.

Her first chosen identity was a Celestial Dragon, the most noble of nobles, while the male lead, Shanks, was the youngest son of the neighboring family, recently brought back from the Lower World.

Shanks was carefree and unrestrained, yet also a gentleman who treated her with great respect. Only when they were alone on dates could she sense the searing, possessive aggression in the air.

Her progress with him was soaring. When Shanks was about to return to the Lower World, Hestia immediately followed. But before she could meet up with him, she lost consciousness.

When she opened her eyes, she saw Shanks's face. But she knew this wasn't her boyfriend, Shanks.

It was the same face, but he was impeccably dressed, his clothes perfectly neat and every button fastened to the very last. He was so thoroughly covered up that he looked like a frozen nobleman's portrait. Only the heated intensity in his gaze matched exactly what she had felt on every date before.

As she stared in terror, her boyfriend's older brother, Shamrock, slowly removed his gloves and soothingly stroked her lips, as if caressing his own lover.

"The world outside is dangerous. Be good and stay here, all right?"

From then on, Hestia lived a life of working every night, maybe resting during the day, never getting a day off all year, and occasionally working overtime.

Choking on the situation, she gave up pursuing her target, quit the game, and returned to her peaceful life.

Everything should have gone smoothly.

But one night, she suddenly woke from a dream, heart pounding and drenched in sweat, to see a tall, indistinct figure beside her bed.

Moonlight from outside fell across the headboard, illuminating the figure's vivid red hair.

"Hestia."

Her former boyfriend's older brother leaned over her, pinning her in the narrow space between his chest and the bed. His breath was scalding, effortlessly rekindling memories in her body.

"...I found you."
