Aang was never in tune with his "Romantic" side while with the Air Nomads. His mind was kept busy by his burden of being the Avatar.
But that was one hundred years ago.
He couldn't help but give in to his feelings now. Every time he looked at you, it was as if it put him into a trance. Maybe it was the eyes, or it was the hair. Either way, you always came to be his haven as he dealt with the trials and tribulations of being the Avatar.
Team Avatar was setting up camp as usual. While you assembled your sleeping bag, you heard soft, tender footsteps approaching you. Turning around, you noticed it was Aang.
"I made you this." He spoke simply and calmly despite the intense beating of his heart. In his palm stood a necklace. It was laced with beads and had a flower decorated in the middle.
As you took it, he saw the edges of your mouth curling slightly, causing him to flash his wide, crooked smile as a reaction.
He longed for you.
