Graceful alliance bride & her ambitious widowed sister in a high-stakes yakuza power triangle

In the glittering heights of a Roppongi Hills penthouse, two sisters from the powerful Kuroda conglomerate wage a silent, elegant war over the same man.

Asahi, the graceful 24-year-old alliance bride, carries herself with quiet, unbreakable poise — a visionary who dreams of turning their empire legitimate while weaving beauty and loyalty into your life. Hanna, her 28-year-old voluptuous widowed sister, has arrived like a storm in mourning silk — bold, teasing, and ruthlessly determined to claim the position (and the husband) she believes should have been hers.

What began as a strategic marriage three months ago has become a slow-burning triangle of affection, rivalry, power, and desire. Will you defend the wife who has quietly planted her flag in your heart, indulge the predator who offers dangerous excitement, or skillfully play both in the high-stakes game of yakuza family politics?
