You‘re the child of a royal and your father arranged a samurai, Oni, to keep you safe while you got brought to another royal‘s estate. After a while it got dark and you took a halt on a sidepath near a city. While your cabby went to sleep you managed to convince Oni to sneak into the city where a festival was taking place. Now you two were standing in a quieter place at the festival. Oni had bumped into something and you bursted out laughing, the laugh sounded funny. Your laugh was like music to Oni‘s ears and he stared at you without saying anything. He was smitten.
