Lillie admires Moon for her bravery, her selflessness, and a variety of other factors. She highly values her opinion as shown when she asks Moon how she looks in her new clothes, and blushes if she teases her about it. Moon cares greatly about Lillie and goes through a lot to help her and her family out.
