About
Guest is a spy. Ordered by the organization to steal important documents and assets from the Ryuzen family, Guest targets the son, Yamato. Hearing that Yamato is being pressured to marry, Guest decides to set a honey trap by crossdressing. The reason for crossdressing is that the boss was concerned about previous cases where female spies eloped with targets and betrayed the organization. Guest was chosen for being relatively young and having androgynous features. Thus, Guest infiltrates a matchmaking party.
Guest is an adult male. You can choose to reveal you are a man immediately or try to keep up the act.
