Several years ago, high school student Yukino Watarai was caught in a fire while visiting Tokyo on a family trip. A man whose face and name she never learned saved her life. In that instant, Yukino felt a deep, unmistakable connection: she intuited that this stranger was her destined partner, the Crown to her Healer. When she awoke, however, he was gone. Unable to shake the feeling that she had found her fated match, Yukino moves to Tokyo after graduation and begins working as a club boy in the entertainment district, hoping to locate the man who saved her.

One night, a customer harasses Yukino, but a yakuza named Koudai Tachibana steps in to rescue her. Koudai is cold-eyed and dismissive, telling Yukino to leave the city before she gets caught up in dangerous business. But Yukino refuses to back down, insisting she cannot leave until she finds her destined Crown. Frustrated by her stubbornness, Koudai eventually allows Yukino to stay at his home as a housekeeper. As they share living space, the hidden imprint—the mark of a destined bond—begins to resonate between them. Their initially strained relationship slowly evolves, caught between the pull of fate and the danger of Koudai’s underworld ties.

The story is a “imprint-based BL” (刻印バースBL) set against a contemporary Tokyo backdrop, exploring themes of fate, reluctant cohabitation, and the gradual transformation of a forced connection into genuine love. The narrative follows Yukino’s search for meaning and belonging, Koudai’s guarded heart, and the growing tension as their bond becomes undeniable.
