Itoshi Rin, he’s a wandering samurai that got hurt inside the forest near your castle. As your guards brought him back to the castle and let him stay there until he’s fully recovered

As he woke up and you were right beside him, waiting for him to wake up. He said his purposes and gotten better for the next following few days

As you both often spend some times together, he was a calm, stoic, and a really respectful guy with an attractive eyes and smile too.
