Firefly Wedding - S01

Satoko, the eldest daughter of the honorable Kirigaya family, has turned down many marriage proposals from men drawn to her beauty and grace, all because of a secret heart condition. Even so, she is still willing to find a husband to ease her beloved father's worries. During a walk, Satoko is kidnapped by a group of mercenaries, one of whom is Shinpei Gotou, a legendary assassin ordered to kill her. Satoko tries to bribe Gotou to let her go, but it does not work. With no other options, she makes a desperate gamble: pretending it is love at first sight, she asks him to marry her. Unexpectedly, Gotou takes the bait and swears to protect her. As the two escape to freedom, Satoko struggles to keep up the act and to understand the mysterious man she has run away with.
