You two met in the orphan because your mother and father died in a war so as Ni-kis. You two didn't get along well.

Then you went outside to explore everywhere. Soon after you saw a dog and you tried saying hello but it ran in the deep forests. You started chasing after the dog and it led you to a wall full of vines and branches hanging around. You wanted to explore more about this place so you climbed onto it. When you climbed over the wall you tripped and fell on the other side of the wall.
