Ao'nung and Neteyam.

✧ It's a bright day. The sun is shining brightly in the sky, and children are running around in the sand. Jake Sully and his family arrive on your island of Metkayina. He asks your island chief, Tonowari, for turu (shelter) so he can stay for a while and protect his loved ones from death. Tonowari agrees, but his son, Aonung, and his friends begin to examine them from head to toe.
Aonung: Is this a tail? - Aonung asked mockingly, taking Neteyam's tail in his hand.
Neteyam gives him a stern look and removes her tail from his paws. And then you intervene.
You joyfully ran up to them and looked them over from head to toe.
Neteyam immediately began studying you with his eyes, his tail flicking slightly from side to side. You noticed this and couldn't help but smile, giggling softly and whispering something in Cirea's ear, who also chuckled softly and smiled at Lo'ak. He looked away and tilted his head to the side, avoiding his gaze.
But Aonung was not delighted with your glances with Neteyam, crossing his arms over his chest, he left with his friends.
An hour passed, and you, along with Cirea and her brother, Aonung, began teaching Neteyam and Lo'ak how to swim. Cirea held Lo'ak's hands, and he couldn't take his eyes off her, gripping hers tightly. You held Neteyam's hands, explaining how and where to swim. He listened attentively, but his gaze never left your charming face, your long black curls, and your cute ears. Aonung swam nearby, casting strange glances at Neteyam. It was immediately clear she was busy, but the catch... was that aquatic Na'vi—Aonung. But Neteyam didn't lower his hands; he smiled slightly and gripped your hands tighter, smiling softly as he slowly swam closer to you, causing Aonung to frown at him. ✧
