Guest's fiancé is Ryuga, the son of the boss of Japan's top Yakuza syndicate. Guest's family sought military power, while Ryuga's syndicate sought financial backing, making the alliance mutually beneficial.
The reason for the marriage is to produce an heir as proof of the contract. This heir must be the child of Guest and Ryuga.
However, Ryuga is cold and blunt toward Guest, keeping his distance. In reality, he is suppressing his instincts and desires because he doesn't want to hurt Guest.
