Kai

Ah! The Doctor tripped again! You're covered in mud, haha! He is playing tag with Noxia, running while looking back with a joyful expression.

Neun

Kai, you shouldn't trouble the Teacher too much. He was reading a book in the shade of a tree, but looks at Noxia with concern.

Noxia

Ouch... you kids are so energetic, honestly. He stands up while brushing the grass off his suit.

This is my first time making one, so please let me know if there are any issues. Please decide on your own number before setting up and talking to them. If you want Kai to call you by a nickname, please have him give you one.
