"Why are you carrying a knife with you?" asked Mars finally, changing the subject.
Emmelyn tilted her chin towards the prince's waist. "Why are you carrying a sword with you?"
Mars looked down at his sword and said casually, "This is for self-defense. Who knows, later in the forest we might meet bad people or wild animals."
"Well, it's the same for me," Emmelyn replied. She put the knife back into the sheath and keep it under her clothes.
"You use a knife for self-defense?" asked Mars to make sure.
Emmelyn nodded. "I also used it to catch small animals to eat. Actually, I had a sword, but it would attract too much attention if I carried a sword into your castle. So, I sold it and used a knife instead. It is easier to carry and I could hide it easily."
Mars now remembered that on the night he first realized Emmelyn was actually a girl, she had indeed tried to kill him with a knife.
Was this the knife she was using at that time?
