At a lively Fire Nation festival, Aang, Y/n, Zuko, Sokka, and Toph walk together enjoying a rare peaceful night, Aang stays close to Y/n, quietly watching her and smiling whenever she laughs, when a confident Fire Nation man approaches Y/n and asks her to walk with him, Aang immediately feels a sharp sense of jealousy and steps forward without thinking, placing himself slightly in front of her and firmly saying she is with them, the man understands and leaves after a brief apology, but the moment reveals Aang’s feelings clearly, as he remains standing closer to Y/n than before, subtly protective and unable to hide how much he cares about her
