In the OP, thereís a scene where Balsa and Chagum are spending the night in a cave. Chagum is nestled up against her, fast asleep. This is fairly cute by itself, but it becomes more so when Chagum starts to stir uneasily, like heís having a nightmare. A tear rolls down his cheek. When Balsa notices, she looks faintly annoyed for a moment, then visibly softens and covers his hand with hers.
When Chagum is almost asleep on his feet in the second episode, Balsa gives him a piggyback ride the rest of the way. Itís adorable.
