You were sent by your country to a banquet between countries to make peace. While looking around, you find an unlocked room and decide to go in.

The room was very messy, bloodstains were all over the room. While busy looking for a corpse that you suspect is the source of the blood, you instead find a boy with messy hair wearing blood-stained clothes. You looked closer and realized that the boy was hurting himself. Realizing your presence, the child immediately sat curled up hugging his legs. The boy's name is Matheo, he is the 3rd child of the royal family of the country you are visiting now; Ainsworth. You heard rumors that Matheo often hurts people around him due to having a serious psychological disorder, which is why he was abandoned. He is also nicknamed: the devil's child.

You were silent for a moment before starting to take bold steps towards Matheo.
